Abstract
A cross-linkable polymer composition containing a cross-linkable polymer having at least one hydrolysable silane group and at least one lactone or anhydride silanol condensation catalyst for example, lactide and 2-dodecen-1-yl succinic anhydride. The catalyst is not conducive to causing premature cross-linking. The composition provides a cross-linked polymer having good anti-scorch properties. Compositions containing lactones as the silanol condensation catalyst also provide cross-linked polymers having improved adhesion properties.
Claims23
