Composition containing atactic polypropylene and a filler treated with an organo-titanate chelate.

摘要

Atactic polypropylene is upgraded to form composites which are workable by conventional thermoplastic shaping techniques by admixing the amorphous polypropylene with a filler which has been treated with an organo titanate chelate. Preferred fillers are the reinforcing fillers such as the silicates and silica. The organo titanate chelates are alpha, omega-alkylene titanates having two non-hydrolyzable groups.
