Definitions
- the invention relates to thermoplastic blends containing:
- thermoplastic blend consisting of:
- A-1) 55 to 75% by weight of a polyester
- A-2) 5 to 25% by weight of a high density or low density polyethylene
- A-3) 10 to 25% by weight of an ionomer composed of at least one copolymer of:
- the invention further relates to molded parts and hollow bodies produced using the thermoplastic mixtures and, in particular, hollow bodies produced by means of blow molding processes using the thermoplastic mixtures.
- thermoplastics such as PET or PBT.
- these mixtures must have certain rheological properties, among other things. What is important here is a good balance between strength and toughness on the one hand and sufficient flowability on the other to best fill the mold.
- the addition of the ionomer increases the compatibility of the more polar PBT and non-polar HDPE with novel ternary blend properties.
- the degree of dispersion of the HDPE in the PBT increases, the crystallization rate of the PBT increases with an increasing proportion of ionomer and overall the ternary phase of HDPE, PBT and ionomer can be regarded as a uniform alloy phase.
- the object of the present invention was now to provide thermoplastic mixtures which are suitable for the production of hollow bodies and molded parts and whose composition on the one hand allows the setting of a balance between flowability, viscosity and crystallization rate that is suitable for processing and on the other hand the required strength and Impact strength in the manufactured hollow bodies and molded parts.
- thermoplastic mixtures defined at the outset were found. Preferred embodiments can be found in the dependent claims.
- thermoplastic mixtures according to the invention contain 30 to 100% by weight of a thermoplastic blend consisting of:
- A-1) 55 to 75% by weight of a polyester
- A-2) 5 to 25% by weight of a high density or low density polyethylene
- A-3) 10 to 25% by weight of an ionomer composed of at least one copolymer of: 3-1) 30 to 99% by weight of ethylene
- thermoplastic mixtures also contain other additives as components B in a proportion of 0 to 70% by weight.
- thermoplastic mixtures contain components A-1 in a proportion of 60 to 70% by weight and components A-3 in a proportion of 10 to 20% by weight.
- a specific polyester, a specific HD or LD polyethylene or a specific ionomer starting material is usually used as components A-1, A-2 and A-3.
- mixtures of such polyester, high-density or low-density polyethylene or ionomer starting materials can also be used.
- even a specific polyester, HD or LD polyethylene or ionomer starting material is inherently a mixture of the respective polyester , HD or LD polyethylene or ionomer reactants.
- polyesters A-1 based on aromatic dicarboxylic acids and an aliphatic or aromatic dihydroxy compound are used.
- Preferred dicarboxylic acids are 2,6-naphthalenedicarboxylic acid, terephthalic acid and isophthalic acid or mixtures thereof.
- Up to 60 mole %, preferably not more than 10 mole %, of the aromatic dicarboxylic acids can be replaced by aliphatic or cycloaliphatic dicarboxylic acids such as adipic acid, azelaic acid, sebacic acid, dodecanedioic acids and cyclohexanedicarboxylic acids.
- Diols having 2 to 6 carbon atoms in particular 1,2-ethanediol, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, 1,4-hexanediol, 1,4- Cyclohexanediol, 1,4-cyclohexanedimethanol and neopentyl glycol or mixtures thereof are preferred.
- a first group of preferred polyesters A-1 are polyalkylene terephthalates, in particular those having 2 to 10 carbon atoms in the alcohol moiety.
- Such polyalkylene terephthalates are known per se and are described in the literature. They contain an aromatic ring in the main chain derived from aromatic dicarboxylic acid.
- the aromatic ring can also be substituted, for example by halogen such as chlorine and bromine or by C 1 -C 4 -alkyl groups such as methyl, ethyl, i- or n-propyl and n-, i- or t-butyl groups.
- polyalkylene terephthalates can be prepared in a manner known per se by reacting aromatic dicarboxylic acids, their esters or other ester-forming derivatives with aliphatic dihydroxy compounds.
- polyesters A-1 are polyalkylene terephthalates derived from alkanediols having 2 to 6 carbon atoms. Of these, particular preference is given to polyethylene terephthalate, polypropylene terephthalate and polybutylene terephthalate or mixtures thereof. Also preferred are PET and/or PBT which contain up to 1% by weight, preferably up to 0.75% by weight, of 1,6-hexanediol and/or 2-methyl-1,5-pentanediol as further monomer units.
- the viscosity number ("VN") of the polyester A-1 is generally in the range from 50 to 220, preferably at least 140 ml/g, in particular at least 145 ml/g (measured in a 0.5% by weight solution in a phenol/o-dichlorobenzene mixture (weight ratio 1:1 at 25°C) according to ISO 1628).
- polyesters whose carboxyl end group content is 0 to 100 mmol/kg, preferably 10 to 50 mmol/kg and in particular 15 to 40 mmol/kg of polyester.
- Polyesters of this type can be produced, for example, by the process of DE-A 44 01 055.
- the carboxyl end group content is usually determined by titration methods (e.g. potentiometry).
- thermoplastic mixtures contain a mixture of polyesters as component A-1, where at least one is PBT.
- the proportion of polyethylene terephthalate, for example, in the mixture is preferably up to 50% by weight, in particular 10 to 35% by weight, based on 100% by weight of A).
- PET recyclates also known as scrap PET
- PET recyclates can optionally be used in a mixture with polyalkylene terephthalates such as PBT.
- Recyclates are generally understood to mean: 1) so-called “post-industrial recyclates”: these are production waste from polycondensation or processing, e.g. sprues from injection molding, start-up goods from injection molding or extrusion or edge sections of extruded sheets or films.
- post-consumer recyclate plastic items that are collected and processed after use by the end consumer.
- plastic items that are collected and processed after use by the end consumer.
- bias-moulded PET bottles for mineral water, soft drinks and juices.
- Both types of recyclate can be in the form of regrind or granules.
