POLYETHYLENE-SYNDIOTACTIC POLYPROPYLENE COMPOSITION AND PROCESSING THEREOF
摘要
A processable polypropylene composition comprising a mixture of a major amount of a syndiotactic polypropylene and a minor amount of polyethylene wax. The syndiotactic polypropylene has a designated recrystallization temperature, an original minor melting peak and a higher original melting peak. The polyethylene wax provides a recrystallization temperature of the mixture that is greater than the recrystallization temperature of the syndiotactic polypropylene alone and also provides for a minor melting peak and a major melting peak of the mixture, which has a temperature difference which is lower than the difference between the original minor melting peak and the original major melting peak of the syndiotactic polypropylene alone. A process for the production of polypropylene product employing a polyethylene-syndiotactic polypropylene composition as described which is heated to provide a plastic mass of the syndiotactic polypropylene and polyethylene which is processed to provide the product.
