DETAILED DESCRIPTION OF THE INVENTION In the present invention, the vinyl chloride copolymer and other specific polymers are finely dispersed during the unmelted stage of the song during normal cross-track processing. The present invention relates to a method for producing a powder-like composite polymer that has good processability and excellent transparency and other physical properties.

In addition to its mechanical properties, it is also economical, so it is used in large quantities for building materials, cable sheathing materials, car widths, etc. In particular, by adding softening agents such as phthalate esters and adipate esters to PVA, molded products that are flexible and elastic at room temperature can be obtained, which is a feature unparalleled by other resins. I'm making it wide. However, depending on the application, impact resistance, heat deformation resistance, etc. are not necessarily sufficient. In addition, a soft PVO composition reprinted with a scalable agent has the disadvantage that the reprinting agent volatilizes and ages, or migrates to other parts and causes harm.

In an attempt to improve the above drawbacks, attempts have been made to mix other polymers during processing or to graft-polymerize vinyl chloride A to other polymers. However, in the former method, P
It is extremely difficult to obtain a composite in which vO and other polymers are finely dispersed, and physical properties such as strength and transparency cannot be sufficiently expressed.In addition, the latter method may not react well depending on the polymer used. In some cases, the desired physical properties may not be obtained due to the reaction not proceeding or crosslinking reaction or deterioration occurring during the reaction.As a result of studies to overcome the various drawbacks mentioned above, the present inventors have found that: By mixing a granular vinyl chloride copolymer with a specific particle size and another specific polymer under specific conditions, both can be finely dispersed, have good processability, and have good transparency and other physical properties. It was discovered that an excellent powder-like composite polymer can be obtained, and the present invention was completed based on this knowledge.

The granular copolymer (A) used in the present invention is usually a copolymer of 20 to 98% by weight of vinyl chloride and 80 to 2% by weight of a monomer copolymerizable with vinyl chloride, and has an average particle size of 20 to 98% by weight. The particle size of the copolymer (A) is more than 40 μm and less than 200 μm, preferably 60 to 150 μm. If the particle size of the copolymer (A) is less than 40 μm, the resulting composite polymer will have poor powder properties; If it exceeds 200 μm, ungelled particles will be present in the obtained composite polymer processed product, which will impair the appearance of the product and reduce its strength, which is not preferable.

Other monomers that can be copolymerized with vinyl chloride include vinyl esters such as vinyl acetate and vinyl stearate, olefins such as ethylene and propylene, vinyl ethers such as isobutyl vinyl ether, 2-ethylhexyl vinyl ether, and lauryl vinyl ether; Examples include acrylic esters such as ethyl acrylate, B-butyl acrylate, and 2-ethylhexyl acrylate, and thumarate esters such as diptyl maleate and di(2-ethylhexyl) maleate.
The preferred monomers are olefins and vinyl ethers. A copolymer of these preferred monomers and vinyl chloride has excellent thermal stability, and therefore provides a composite polymer with excellent thermal stability.

Such a copolymer may be produced by any method such as emulsion polymerization, suspension polymerization, bulk polymerization, or gas phase polymerization, but suspension polymerization is preferable.

In the present invention, the sum of monomer moieties other than vinyl chloride of the polymer (Bl and copolymer (Al) is 10 to 400 parts by weight based on the chloride and second part IDDJi of the copolymer (A),
It is preferably used in an amount of 20 to 300 parts by weight. If this sum is less than 10 parts by weight, the obtained composite polymer will have poor flexibility, while if it exceeds 400 parts by weight, it will be too soft or have defects in physical properties. ) The solvent (0) is incompatible with water, is a poor solvent of pvo, and has 1
Examples include vinyl chloride, vinyl fluoride, vinyl bromide and other vinyl halides, vinylidene chloride, trichloroethylene, fuchlorohexane, and benzene. Of course, it is also possible to use two or more of these in combination. Among these, vinyl chloride is polar, so there is a wide range of options for other polymers; its low boiling point allows it to remain in the polymer; it is easy to recover; and it is inexpensive.

If the amount is less than 1 part by weight, the copolymer (Shu) (polymer dissolved in C1 (Bl) will stick and become block-like, making it impossible to obtain a granular composite polymer. Although not limited to this, in general, the amount of composite polymer obtained in the production is less than 500 parts per 100 parts by weight of the copolymer and polymer (B), which is inefficient.
