Abstract
A composition which is a uniform blend of 50-90 weight % of a polyamide melt-processable within the temperature range of 180.degree.-210.degree. C. and 50-10 weight % of recovered plasticized polyvinylbutyral, optionally also containing a small amount of an elastomeric ethylene copolymer carrying pendant succinic anhydride groups, has high impact strength and good flexural modulus. The polyamide in these compositions forms the matrix, and the plasticized polyvinylbutyral and any elastomer present form the dispersed phase. Such compositions have good barrier properties and are useful, among others, in applications where good toughness is required, for example, in packaging subjected to rough handling.
