Title:
PROCESS FOR THE PRODUCTION OF POLYOLEFIN MOLDINGS
Document Type and Number:
WIPO Patent Application WO/1998/018611
Kind Code:
A1
Abstract:
A process for effectively producing polyolefin moldings having high strengh and high modulus and capable of dispensing with the step of removing a flowability improver. The process is characterized by melt-molding a composition comprising as the main components 100 parts by weight of a high-density polyolefin such as high-density polyethylene and 1 to 30 parts by weight of a polymerizable monomer or oligomer having an affinity for the high-density polyolefin into a sheet or film, subjecting the same to rolling and stretching, and then polymerizing the same contained in the sheet or film.
