ABSTRACT:
Novel polymer blends are provided comprising a linear low density copolymer of ethylene with an olefin containing 4 to 10 carbon atoms (LLDPE) compounded with minor amounts of an at least partially isotactic, partially crystalline butene-1 polymer comprising at least about 80 wt. % of polymerized butene-1, and an ABS resin. The blends can be fabricated with better processability into blown films having improved impact and MD tear resistance properties.
