STABILIZER COMPOSITION FOR SYNTHETIC RESIN

WIPO Patent Application WO/2007/023919

A1

Disclosed is a stabilizer composition for synthetic resins which is capable of improving thermal stability and light stability in a wide range of synthetic resins. This stabilizer composition can be uniformly dispersed in the synthetic resins, thereby enabling to obtain transparent synthetic resins. Specifically disclosed is a stabilizer composition for synthetic resins having a structure wherein a zinc oxide having a number average particle diameter of 0.5-20 nm is modified with a mercapto group-containing compound having a number average molecular weight of 1,000-50,000. Since the stabilizer composition for synthetic resins has a small particle diameter and can be uniformly dispersed in various synthetic resins, the resulting synthetic resin compositions are able to form a transparent film. In addition, this stabilizer composition has effects of remarkably improving thermal stability and light stability of various resins.
