Abstract

Resinous compositions comprising blends of linear polyesters such as poly(butylene terephthalate) with nitrile rubbers have very high impact strengths. The blends may also contain other polymers such as elastomers free from nitrile structural units, addition polymers of olefins or chlorinated olefins, or polylactones; such other polymers frequently improve properties such as gloss and low temperature impact strength.
