Cross-linkable compositions based on vinyl chloride cross linkable copolymers and elastomers
Abstract
Abstract THE CROSS-LINKABLE COMPOSITION CONTAINS FROM ABOUT 1 TO 18% BY WEIGHT OF ONE OR MORE ELASTOMERS AND 99 TO 82% BY WEIGHT OF A CROSS-LINKABLE VINYL POLYMER BASED ON VINYL CHLORIDE. THE CROSS-LINKABLE VINYL POLYMER IS OBTAINED BY POLYMERIZATION OF 3 TO 50 PARTS BY WEIGHT OF A MIXTURE OF A DIOLEFIN AND ONE OR MORE MONOMERS CHOSEN FROM THHE NITRILES AND ESTERS OF UNSATURATED MONOCARBOXYLIC ACID AND UNSATURATED POLYCARBOXYLIC ACID, IN THE PRESENCE OF 100 PARTS BY WEIGHT OF A COPOLYMER OF VINL CHLORIDE AND A MONOMER CONTAINING AT LEAST 8 CARBON ATOMS AND WHICH IS A VINYL ESTER OF A MONOCARBOXYLIC ACID, AN ESTER OF AN UNSATURATED MONO- OR POLYCARBOXYLIC ACID OR AN ALKYL VINYL ETHER. THE CROSS-LINKABLE COMPOSITION HAS EXCELLENT ELASTICITY AND PROCESSABILITY AT LOW TEMPERATURE AND IS CROSS-LINKED RAPIDLY AND COMPLETELY TO PRODUCE SEMI-RIGID PRODUCTS WHICH HAVE GOOD DIELECTRC PROPERTIES AND EXCELLENT MECHANICAL PROPERTIES.
