Title:
BRIDGEABLE COMPOSITION AND INSULATION FOR ELECTRIC WIRE OR CABLE BY EXTRUSION COATING THEREWITH
Document Type and Number:
Japanese Patent JPS60170628
Kind Code:
A
Abstract:
A crosslinkable composition comprising a thermoplastic silyl modified polymer and a silanol condensation catalyst pre-supported on a finely divided solid material. The silyl modified polymer contains hydrolysable silane groups introduced into the polymer by copolymerisation, grafting or transesterification. The finely divided solid material has a particle diameter not greater than 20 microns and is preferably selected from porous materials which do not melt or decompose during thermoforming. The silanol condensation catalyst is preferably a dialkyl tin dicarboxylate. The use of a silanol condensation catalyst which is pre-supported reduces premature crosslinking on extrusion of the composition.
