MOLDED POLYOLEFIN AND PROCESS FOR PRODUCING THE SAME

摘要

A molded polyolefin which is excellent in mechanical properties and dimensional stability under heating and can be easily produced without the use of a reinforcement of a different kind, e.g., glass fibers. The molded polyolefin comprises a stretched polyolefin material so as to have an average coefficient of linear expansion at 20~C to 80~C of 5x10-5 (/~C) or lower. The process for producing the same comprises the steps of depositing a lowmolecular compound in which polyolefins are soluble on the surface of a stretched polyolefin material having an average coefficient of linear expansion at 20~C to 80~C (C of 5x10-5 (/~C) or lower and then bonding the deposit by pressing and heating.
