Abstract
A process for producing a polymer crosslinkable by exposure to moisture in the presence of a hydrolysis/condensation catalyst comprising blending (i) a thermoplastic base polymer, (ii) a solid carrier polymer containing a silane, and (iii) a free radical generator; heating and mixing (i), (ii) and (iii) together at a temperature above the crystalline melting point of said base polymer; optionally, a free-radical generator, hydrolysis/condensation catalyst, and other additives are contained in the solid carrier polymer.
