ABSTRACT:
The invention provides a method of increasing the elasticity of moisture-cured elastomers, which comprises adding to alkoxy-cross linking one-component compositions comprising an alkoxysilane-terminated polymer (A) containing end groups of the formula (1)in-line-formulae description="In-line Formulae" end="lead"?-A-Si(R)a(CH3)3-a  (1)in-line-formulae description="In-line Formulae" end="tail"?a silane (B), of the general formula (2)in-line-formulae description="In-line Formulae" end="lead"?X—CH2—Si(R)2(CH3)  (2)in-line-formulae description="In-line Formulae" end="tail"?whereA is a divalent hydrocarbon radical,R is a methoxy or ethoxy group,X is a group R″O—, R″NH—, R′—O—CO—NH, R′—NH—CO—NH— or halogen,R″ is hydrogen, an optionally halogen-substituted C1-18hydrocarbon radical or a radical R′—O—CO— or R′—NH—CO,R′ is an optionally halogen-substituted C1-8hydrocarbon radical, anda is 1, 2 or 3.
