Abstract

PURPOSE:To obtain the titled composition of high processability and mechanical strength, with small permanent set under both compressive and tensile force, by incorporating vinyl chloride resin with specific acrylonitrile-styrene-butadiene graft copolymer and plasticizer. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of vinyl chloride resin with (B) 30-150pts.wt. of an acrylonitrile-styrene-butadiene graft copolymer prepared by graft polymerization of both acrylonitrile (AN) and styrene (ST) to a gel-like polybutadiene (PBd) containing 50- 100wt% of toluene-insoluble gel content so as to satisfy the following two equations: (i) {PBd/(AN+ST+PBd)}X100=30-70wt%, (ii) {AN/(ST+AN)}X100= 15-45wt% and (C) plasticizer.

Conventionally, soft vinyl chloride resins containing plasticizers have been widely used as materials for hoses, gaskets, leather, films, wire coatings, and the like. However, this soft vinyl chloride resin has the disadvantage that its shape retention at high temperatures and permanent deformation resistance are significantly inferior to that of vulcanized rubber. As an improvement method, for example, if a high polymerization degree vinyl chloride resin with an average degree of polymerization of 2500 to 4000 is used, compression set (JIS
K-6301, 70°C x 22 Hr) reduces the coefficient to nearly 50 compared to the 60 to 70 coefficient of conventional soft vinyl chloride resin, but it can be used as a material for hoses, gaskets, etc. that require even lower permanent set characteristics. is inappropriate. Therefore, the average degree of polymerization is 4.000 to 10, which is even higher.
.. Even if a vinyl chloride resin of 0,000 or more than IO,000 is used, not only the expected low permanent set cannot be obtained, but also
It is undesirable because it has the drawbacks of low productivity during production of vinyl chloride resin (and poor molding performance). When an acrylonitrile-butazene copolymer containing a plasticizer is blended with a vinyl chloride resin, the viscosity of the blend increases due to the good compatibility between the acrylonitrile-butadiene copolymer and the vinyl chloride resin, resulting in poor fluidity. There is a drawback that the surface smoothness during extrusion molding or injection molding is poor.

As a result of intensive studies in order to improve the above-mentioned drawbacks, the present inventor found that a composite material composition containing a specific acrylonitrile-styrene-butatsuene graft copolymer, a vinyl chloride resin, and an OT plastic agent as the main components is a vinyl chloride-based resin. The present invention has been achieved by discovering that the permanent set resistance under compression and tension can be significantly improved while retaining the advantages of resin in processability and mechanical strength.
