Method of molding a polymer composition containing a tetraalkenyl orthosilicate

摘要

A method for producing molded articles by supplying to a mold a powdered thermoplastic material; heating the mold to fuse the material and cooling the mold to cause the fused thermoplastic material to solidify. The article is molded from a high density monoolefin thermoplastic polymer which contains a catalyst residue, a crosslinking amount of an acetylinic diperoxy compound and a tetraalkenyl orthosilicate compound. The molded article has at least one of increased crosslinking, lowered bubble formation and increased storage modulus.
