Resin composition including a saponified ethylene-vinyl acetate

A method of producing shaped articles having excellent impact resistance which includes melt-molding a composition derived from a saponified ethylene-vinyl acetate copolymer (A) by incorporating therein an ethylene-propylene copolymer elastomer (B) and a graft polymer (C) obtained by grafting an ethylenically unsaturated carboxylic acid or a derivative thereof to a polyolefin resin and reacting the resulting grafting product further with a polyamide oligomer or polyamide.

Method of producing shaped articles having excellent impact resistance

This invention provides a halogen-containing thermoplastic resin composition comprising a halogen-containing thermoplastic resin (A), a melt-moldable vinyl alcohol polymer (B) and a polyesteramide (C), the proportions of (B) and (C) being 0.1 to 100 parts by weight and 0.1 to 10 parts by weight, respectively, based on 100 parts by weight of (A). The component (C) improves the compatibility between the components (A) and (B).

Halogen-containing thermoplastic resin composition

This invention provides a halogen-containing thermoplastic resin composition comprising a halogen-containing thermoplastic resin (A) consisting of 100 to 0.1 weight percent of a thermoplastic polyurethane-vinyl chloride graft polymer (a1) with a polyurethane content of 10 to 90 weight percent which is produced by polymerizing vinyl chloride in the presence of a thermoplastic polyurethane and 0 to 99.9 weight percent of another halogen-containing polymer (a2) and a melt-moldable vinyl alcohol polymer (B), the proportion of melt-moldable vinyl alcohol polymer (B) being in the range of 0.1 to 100 parts by weight to 100 parts by weight of halogen-containing thermoplastic resin (A).

A halogen-containing thermoplastic resin composition comprising a halogen-containing thermoplastic resin (A), a metallic soap (B) and an ash- and alkali metal-lean ethylene-vinyl acetate copolymer hydrolysate (C) having an ethylene content of 20 to 75 mole percent, a degree of saponification not less than 50 mole percent, an ash content not exceeding 300 ppm and an alkali metal content not exceeding 200 ppm, the proportions of (B) and (C) based on 100 parts of weight by (A) being 0.1 to 5 parts by weight and 0.1 to 5 parts by weight, respectively. The composition may further include, in addition to (A), (B), and (C) mentioned above, at least one compound (D) selected from the group consisting of .beta.-diketone compounds, organic phosphorous esters and aminocarboxylic acid compounds, the proportion of (D) based on 100 parts by weight of (A) being 0.05 to 5 parts by weight, and/or at least one compound (E) selected from the group consisting of phenol derivatives and epoxy compounds, the proportion of (E) based on 100 parts by weight of (A) being 0.01 to 5 parts by weight.
