摘要

"Pelu00ecculas biaxially - oriented and containers of trainees using a material obtained by mixing a molten substance, and the polymeric material suitable for the preparation of the same.Compositions composed of a polyester resin and a polyamide acid derivative of an acid with 6 to 22 carbon atoms and M - xilileno diamine having gas barrier properties of high level.Obtained by mixing is in the molten state resin polyester pre mixed with an acid dianhydride tetracarboxylic dianhydride and a polyamide.Operating under such conditions sufficient to obtain the reologicamente polymer components are compatible with each other.The compositions are suitable for preparing biaxially oriented containers and films.
