Silane grafted polyethylene with a reduced level of extractable methanol

Номер: US20120128910A1
Автор: Carl M. Mahabir
Принадлежит: Lubrizol Advanced Materials Inc

A hydrophobic molecular sieve having a pore size of about 5 Å can be blended into a silane grafted crosslinkable polyethylene to reduce the level of extractable methanol present in articles made with such polymeric compositions after crosslinking. The molecular sieve apparently acts to “lock-up” the methanol generated as a by-product of the crosslinking reaction without compromising the desirable chemical or physical properties of articles that are manufactured with the crosslinked polyethylene.
