Document Type and Number:
WIPO Patent Application WO2001049789
Kind Code:
A8
Abstract:
A moisture curable composition capable of cure to an elastomeric body, comprising a polymeric material having not less than two hydroxyl or hydrolysable groups an alkoxysilane curative and a catalyst comprising: a mixture and/or reaction product of a compound (i) selected from M[OR]4 and M[OR']x[Z]z, wherein M represents a metal having a valency of 4 selected from Group IVB of the Periodic Table, preferably titanium or zirconium. Each R and R' may be a primary, secondary or tertiary aliphatic hydrocarbon or the group SiR<9>3; and a compound (ii) of the general formula A-C(=O)R<1>-C(=O)-B wherein R<1> is a methylene group or a substituted methylene radical, A is selected from -(CX2)nC(R<2>)3 wherein n is from 0 to 5, and an adamantyl group or a derivative thereof; B is selected from the group of -(CX2)tC(R<2>)3 wherein t is from 0 to 5; a monovalent alkyl group having from 1 to 6 carbon atoms; and OR<3>, wherein R<3> is selected from the group of -(CX2)tC(R<2>)3 and a monovalent alkyl group having from 1 to 6 carbon atoms; wherein each X is the same or different and is selected from the group of a halogen radical and hydrogen, each R<2> is the same or different and is selected from the group of a halogen radical and an alkyl radical having one to eight carbon atoms, and when n is greater than 0 at least one of X or R<2> is a halogen radical.
