VINYL POLY (VINYL CHLORIDE) COMPOSITIONS STABILIZED BY LAURYLSTANIC COMPOUNDS, APPLICATION THEREOF AND METHOD FOR STABILIZING MOLDING MATERIALS

摘要

THE INVENTION CONCERNS VINYL CHLORIDE HOMOPOLYMER-BASED COMPOSITIONS THAT ARE STABILIZED BY ORGANIC TIN COMPOUNDS. These novel compositions consist of 20 to 80% of HOMOPOLYMER OF VINYL CHLORIDE AND 80 TO 20 OF ONE OR MORE COPOLYMERS, SUCH AS COPOLYMERS POLYSTYRENEPOLYETHYLENEBUTENE, ACRYLATECAOUTCHOUC, ACRYLATECAOUTCHOUCSTYRENE, ACRYLONITRILESTYRENEACRYLATE, ABS, NBR, NAR, SAN AND EVA, AND THEY CONTAIN, AS STABILIZING, AT LEAST ONE COMPOUND TIN COMPLYING WITH ONE OF THE FORMULAS: (N-CH) SNS (CH) COOR (N-CH) SNS (CH) COORDANS WHICH ARE NONE EQUAL TO 1 OR 2 WHILE R AND R REPRESENT EACH ALKYL These compositions are well resistant to heat and are particularly suitable for the manufacture of hollow sheets and articles which can be used in the automotive industry. / P
