Process for crosslinking olefin polymers

A Henmi, +3 more
TLDR
In this article, the authors describe a process for co-slinking an OLEFIN POLYMER or COPOLYMER in the presence of a free RADICAL CATALYST and a CROSSLINKING ADJUVANT.
Abstract: 
A PROCESS FOR CROSSLINKING AN OLEFIN POLYMER OR COPOLYMER CAPABLE OF BEING MOLDED BY HEATING THE OLEFIN POLYMER OR COPOLYMER IN THE PRESENCE OF A FREE RADICAL CATALYST AND A CROSSLINKING ADJUVANT, CHARACTERIZED IN THAT THE CROSSLINKING ADJUVANT IS TRIALLYL TRIMELLITATE AND/OR TRIMETHALLYL TRIMELLITATE. THE USE OF THE ABOVE-MENTIONED CROSSLINKING ADJUVANT RESULTS IN SUCH ADVANTAGES THAT THE CROSSLINKING EFFICIENCY IS ENHANCED AND THE CROSSLINKED POLYMER OR COPOLYMER IS IMPROVED IN HEAT RESISTANCE, CHEMICAL RESISTANCE, MECHANICAL STRENGTH AND ELECTRICAL PROPERTIES,
