The orientation pyro pyrene polymer film which improves oxygen barrier Characteristic

摘要

(57) Abstract Topic The polypropylene film where oxygen barrier Characteristic is improved is offered SolutionsImprovement of the oxygen barrier in the polypropylene polymer constituent where the film is produced, is achieved by introducing the graft copolymer which consists of the crystal Characteristic propylene polymer material mainly. Graft of the polymerization monomer material of the group where the graft copolymer, the styrene and the p alkyl styrene, the acrylic Acid, the arukuakuriru Acid and the arukiruarukuakuriru Acid, accompanies the acrylonitrile and ethylene and vinyl acetate, or does not accompany it is something which is done.
