CROSSLINKABLE POLYETHYLENE COMPOSITION

A combination of vinyl trimethoxysilane and vinyl triethoxysilane can be grafted onto polyethylene to produce a polyethylene graft terpolymer that can be crosslinked without a significant reduction in crosslinking rates relative to vinyl triemethoxysilane grafted polyethylene. The combination of vin...

Zusammenfassung:	A combination of vinyl trimethoxysilane and vinyl triethoxysilane can be grafted onto polyethylene to produce a polyethylene graft terpolymer that can be crosslinked without a significant reduction in crosslinking rates relative to vinyl triemethoxysilane grafted polyethylene. The combination of vinyl trimethoxysilane and vinyl triethoxysilane apparently act synergistically. While byproduct methanol from crosslinking with trimethoxysilane is very undesirable in some products, byproduct ethanol from crosslinking is less hazardous, especially at ppm levels.
