US Patent 7847005 Stabilized halogen-containing resin composition

A stabilized halogen-containing resin composition containing a halogen-containing resin and a stabilizer component comprising a complex (A) of a metal silicate and a calcium hydroxide compound and at least one member selected from a hydrotalcite (B) and a tin-containing stabilizer (C), which composition has synergism (multiplier effect), overcomes the problems of decreases, due to the high loading of a stabilizer, in the inherent mechanical strength and electrical characteristic of the resin and makes reduction of cost of stabilizers, and a process for producing the complex (A).
