Abstract
Polypropylene resins are improved in mechanical properties and in rigidity without loss in thermal processability when blended with polyphthalamide resins together with a minor amount of a carboxylated polyolefin compatibilizing aid. Filled compositions, including glass-filled polypropylenes are similarly benefited when blended with a polyphthalamide and a carboxylated polyolefin compatibilizing aid.
