Abstract
A resin composition comprising an ethylene-unsaturated ester copolymer and metakaolin, wherein the ethylene-unsaturated ester copolymer comprises structural units derived from ethylene and structural units derived from an unsaturated ester and the content of the structural units derived from the unsaturated ester is 20 to 35% by weight where the total content of the structural units derived from ethylene and the structural units derived from the unsaturated ester is taken as 100% by weight, and the resin composition comprises 0.001 to 5 parts by weight of the metakaolin per 100 parts by weight of the ethylene-unsaturated ester copolymer.
Claims6
A resin composition comprising an ethylene-unsaturated ester copolymer and metakaolin, wherein the ethylene-unsaturated ester copolymer comprises structural units derived from ethylene and structural units derived from an unsaturated ester and the content of the structural units derived from the unsaturated ester is 20 to 35% by weight where the total content of the structural units derived from ethylene and the structural units derived from the unsaturated ester is taken as 100% by weight, and
- the resin composition comprises 0.001 to 5 parts by weight of the metakaolin per 100 parts by weight of the ethylene-unsaturated ester copolymer.
A resin pellet in which metakaolin attaches to the surface of an ethylene-unsaturated ester copolymer pellet, wherein the ethylene-unsaturated ester copolymer that forms the ethylene-unsaturated ester copolymer pellet is an ethylene-unsaturated ester copolymer that comprises structural units derived from ethylene and structural units derived from an unsaturated ester wherein the content of the structural units derived from the unsaturated ester is 20 to 35% by weight where the total content of the structural units derived from ethylene and the structural units derived from the unsaturated ester is taken as 100% by weight, and
- the metakaolin attaches in an amount of 0.001 to 5 parts by weight per 100 parts by weight of the ethylene-unsaturated ester copolymer pellet.
