Composition with improved crosslinking |
摘要 |
A crosslinking composition including, (a) a major amount of a high molecular weight linear oligomer with at least one functional group and a number average molecular weight per functional group of at least about 1000; (b) a crosslinking agent reactive with the functional groups of the high molecular weight linear oligomer; and (c) a low molecular weight di-(poly)-functional compound having a number average molecular weight per functional group of less than about 400, the functional groups of the low molecular weight di-(poly)-functional compound also being reactive with the cross-linking agent. Crosslinking of the high molecular weight oligomer in the presence of a small amount of the low molecular weight di-(poly)-functional compound provides a crosslinked composition displaying an improved balance of hardness and flexibility.
