  • Patent number: 4574133
    Abstract: A crosslinkable composition comprising a silyl modified ethylene (co)polymer, a defined phosphorus or antimony compound and optionally a silanol condensation catalyst. The silyl modified polymer has hydrolysable silane groups introduced therein by copolymerization grafting or transesterification. The phosphorus or antimony compound (e.g. tributyl phosphite) reduces premature crosslinking during extrusion of the composition.

  • Patent number: 4517115
    Abstract: A vinyl halide resin stabilizer composition which essentially contains:(a) an antimony organic sulfur-containing compound, for example, antimony mercaptoacid esters, antimony alkyl mercaptides, and the like,(b) an alkaline earth metal salt of a carboxylic acid, such as calcium stearate, and(c) an alkali metal carbonate, such as sodium carbonate.These compositions synergistically contribute to the dynamic processing stability of vinyl halide resin compositions. Rigid polyvinyl chloride compositions are stabilized against dynamic processing conditions of heat and shearing forces.
