Provided is a resin mixture, comprising: polyolefin (A); a saponified ethylene-vinyl acetate copolymer (B); and an acid modified olefin-vinyl carboxylate copolymer (C), wherein the acid modified olefin-vinyl carboxylate copolymer (C) has an olefin content of from 50 to 95 mol %, and a difference between an ethylene content of the saponified ethylene-vinyl acetate copolymer (B) and the olefin content of the acid modified olefin-vinyl carboxylate copolymer (C) is within a range of from 20 to 70 mol %. This enables to provide a resin mixture that contains polyolefin and an EVOH, and even in continuous melt molding over a long period of time, has a less amount of screw buildup of a degraded material and also is reduced in generation of fish-eyes, cords, and streaks in a molded product obtained therefrom.

Copolymer and medical material containing the same

A copolymer is capable of being immobilized on a base material while maintaining a high antithrombotic property persistently without having to introduce heparin or an anticoagulant drug to the surface thereof. The copolymer includes monomer unit A, monomer unit B, and monomer unit C, wherein monomer unit C has a mole fraction of 0.5-40% with respect to the total amount of all constituent monomer units.
