ABSTRACT:
Hindered phenol stabilized, stereoregular polymers of branched, higher alpha-olefins can be modified with unsaturated silanes, carboxylic acids, and/or carboxylic acid anhydrides in the presence of a free radical generator in the polymer melt. These polymers can also contain additional additives, such as glass fibers. An aliphatic thio compound is added after the grafting procedure for maximum beneficial effect.
