PURPOSE:An improving agent having good dispersibility in a thermoplastic resin (e.g., vinyl chloride resin) and capable of providing a resin composition excellent in impact resistance, and moldability, comprising a multilayer (at least three-layered) graft copolymer in which the Tg (glass transition temperature) of the outermost layer is 0 deg.C or below. CONSTITUTION:An impact resistance-improving agent prepared by forming, by graft-polymerization, at least two graft layers on a polybutadiene elastomer (with the weight ratio of other vinyl compounds to butadiene of at most one) containing 0-5wt% crosslinking agent. Each of the graft layers is formed from a polymer of an alkyl (meth)acrylate, aromatic vinyl compound, vinyl cyanide compound of butadiene, containing 0-5wt% crosslinking agent, and the Tg of the polymer of the outermost layer is 0 deg.C or below, and the Tg of the polymer next to the outermost layer is 60 deg.C or above.

The present inventors have demonstrated that such multilayer graft copolymers can be homogeneously dispersed in PVC'@4. The glass transition temperature (hereinafter abbreviated as Tg) of the outermost layer is 0 compared to the conventionally known multilayer graft copolymer. The multilayer graft co-TJf coalescence, which is below ℃, is blended with PVC [7 and mixed during molding n,! Not only does the crystallization condition remain good even in the case of crystalline moldings, but the multilayer kraft copolymer melts quickly even in the case of low mixing and shear stress, and gels easily. It was discovered that the dispersion state is extremely good, the strength is 53% under a wide range of molding conditions, the processability is good, and a molded product with excellent surface gloss can be obtained. The gist of this is that polybutadiene or butadiene 50M# has a crosslinking agent of 0 to 5 weights.

When it is used in an amount exceeding 5% by weight, the diene elastic material (A) or layer (3), which is the elastic material layer, is responsible for the elastic properties. Both are undesirable because the effect of improving impact resistance decreases.The proportion of the polyfunctional crosslinking agent in each layer is determined by the coagulation of the emulsion polymer latex during the production of the poly-N graft copolymer. Taking into consideration the impact resistance of the multilayer graft copolymer, the weight ratio is preferably in the range of 01 to 3.

The impact modifier of the present invention is blended into the thermoplastic resin at a ratio of 3 to 50 parts by weight per 100 parts by weight of the thermoplastic resin. A blend f;J @ of less than 5 parts by weight is not preferred, since the effect of improving impact resistance is small, and if the lifting platform exceeds 5 parts by weight, the mechanical properties inherent to the thermoplastic resin will be impaired. Here, the thermoplastic resin includes PVA, polycarbonate resin, polyester resin, acrylonitrile-styrene resin, methyl methacrylate-styrene resin, and the like. As PVO, in addition to polyvinyl chloride, a vinyl chloride-based copolymer consisting of vinyl chloride 7077 (by weight % or more) can be used.
