Molded polyolefin parts of improved dimensional stability at elevated temperatures and improved stiffness

摘要

Molded polyolefin articles of improved dimensional stability at elevated temperatures and improved stiffness and consist of mixtures of modified propylene polymers, which are synthesized by free radical coupling reactions or polymer-like reactions of functionalized polypropenes, and of unmodified propylene polymers, crystalline copolymers of propylene and alpha -olefins, elastic copolymers of ethylene and alpha -olefins, largely amorphous polypropylenes, non-isotactic propylene homopolymers, and auxiliary materials. The molded polyolefin articles, produced by blow molding or injection molding are suitable for use in the packaging industry, for use in the domestic appliances industry, to meet the requirements of laboratories and hospitals, for gardening and agricultural implements, for transporting containers for components in the automobile industry, and for components of machines and of electric and electronic equipment.
