Polycarbonate Composition with Improved Mechanical Properties
FIELD OF THE INVENTION
The present invention relates to the field of chemistry, in particular, to a polycarbonate composition.
BACKGROUND OF THE INVENTION
At present, polycarbonate is one of the widely-used thermoplastics in industrials such as automobile industry, appliance industry, and electronics industry. This is because polycarbonate has many excellent properties such as heat resistant, transparency, flame retardant, form stability, electrical insulation, gloss, and high glass transition temperature. However, some properties of polycarbonate result in limitation to its use such as corrosion resistant from solutions and chemicals and high melt viscosity. This limitation causes the injection process to be done at high temperature in order to reduce viscosity of polycarbonate during the process. Therefore, there have been attempts to overcome said problems by blending polycarbonate with other polymers to form polymer blends or polymer alloys.
It has been known that blending of acrylonitrile-butadiene-styrene polymer (ABS) with polycarbonate can improve the rheological property and processability, while maintaining high impact strength. However, polycarbonate/acrylonitrile-butadiene-styrene polymer (PC/ABS) normally results in a reduction of stability when exposed to heat, and an increase of brittleness.
There has been reported that blending of styrene-acrylonitrile copolymer (SAN) with polycarbonate/acrylonitrile-butadiene-styrene polymer could improve the rheological property.
This leads to a possibility to form parts of automobile and improvement of some mechanical
2017100888 09 Mar 2018
Page 2 of 17 properties of polymer. However, it has been found that the increased proportion of styreneacrylonitrile copolymer might reduce the polymer’s heat resistant and strength. Therefore, there have continuously been attempts to overcome said problems, meanwhile maintaining other good properties.
EP0700968 disclosed the thermoplastic composition comprising 60 to 98 % by weight of polycarbonate, 2 to 40 % by weight of acrylonitrile-butadiene-styrene graft polymer, and to 20 % by weight of styrene-acrylonitrile copolymer. Aromatic diphosphate, phosphorous compound, and fluoric resin were added to improve flame retardant property. However, said patent did not disclose the mechanical properties of the obtained polymer.
US8124683 disclosed the polycarbonate composition comprising 40 to 95 parts by weight of polycarbonate, 2 to 40 parts by weight of graft polymer, 1 to 30 parts by weight of vinyl copolymer, and 3 to 40 parts by weight of polyester copolymer. It was found that polyester copolymer provided improved mechanical properties, including tensile strength and impact strength.
EP0433723 disclosed the polycarbonate composition comprising about 36 % by weight of polycarbonate, about 18 % by weight of acrylonitrile-butadiene-styrene polymer, about 46 % by weight of styrene-acrylonitrile copolymer, and about 0.1 to 2 % by weight of oxidized polyethylene lubricant. It was found that said composition had better mechanical properties.
However, tensile strength was not high, yielding about 52 MPa.
EPI071726 disclosed the polycarbonate composition comprising 20 to 90 parts by weight of polycarbonate, 4.5 to 70 parts by weight of vinyl copolymer, 5 to 70 parts by weight of graft polymer and 5 to 95 parts by weight of graft base having average particle size between 0.05 to 5 microns. Necessarily, compatibilizer comprising polymer resin with molecular weight at least
2017100888 09 Mar 2018
Page 3 of 17
21,000 g/mol and comprising secondary amine group was added. It was found that the polycarbonate composition according to said patent had better energy absorption property at low temperature.
EP0728161 disclosed the polycarbonate composition comprising 20 to 85 % by weight of polycarbonate having molecular weight of more than 20,000 g/mol, 1 to 30 % by weight of acrylonitrile-butadiene-styrene polymer, and 1 to 40 % by weight of styrene-acrylonitrile copolymer. Preferably, said styrene-acrylonitrile copolymer had molecular weight between
40,000 to 80,000 g/mol and comprising 65 to 95 % by weight of aromatic vinyl monomer and 8 to 35 % by weight of vinyl cyanide monomer. However, it was found that said composition did not have high impact strength; that is about 600 J/m.
From the reasons mentioned above, this invention aims to develop the polycarbonate composition with improved mechanical properties while maintain the high thermal property in order to promote its variety of applications especially for using as parts in automobile industry.
