Use of cyanogen acetylureas for stabilising antistatic organic plastics containing halogen

摘要

Methods of stabilizing antistatically-finished, halogen-containing organic plastics are described, wherein the methods comprise: (a) providing a cyanoacetylurea of the general formula (I): NC-CH2-CO-N(R<1>)-CO-NH-R<2> (I) wherein R<1 >and R<2 >each independently represent a hydrogen atom, a C1-8 alkyl group which can be branched or unbranched and linear or cyclic, or a C6-18 aryl group which can be substituted by one or more C1-6 alkyl groups; and (b) combining the cyanoacetylurea and the antistatically-finished, halogen-containing organic plastic. Stabilizer compositions containing a cyanoacetylurea and PVC formulations containing such stabilizers are also described.
