COMPOSITION A BASE DE MALEATES D'ORGANOETAIN UTILISABLE POUR STABILISER ET LUBRIFIER DES POLYMERES THERMOPLASTIQUES. PROCEDE D'OBTENTION DE LADITE COMPOSITION

摘要

The invention concerns a composition of organotin maleates resulting from reacting a mixture of an alcohol or of an epoxyalkane of low molecular weight and of an alcohol or of an epoxyalkane of high molecular weight with maleic anhydride, then in contacting the resulting medium with a dialkyltin oxide. The invention also concerns the polyvinyl chloride (PVC) stabilised and lubricated with said composition with base of organotin maleates as well as the rigid extruded objects formed from said PVC compositions.
