CPC classification number: C08K5/00 , C08L55/02 , C08L2666/02

Abstract: ABS RESINS HAVE IMPROVED STABILITY AGAINST DEGRADATION DUE TO HEAT AND OXYGEN BY ADDITION OF A BALANCED STABILIZER COMPOSITION WHICH MAINTAINS INITIAL COLOR AND IMPACT STRENGTH, MINIMIZES MELT FLOW CHANGES, AND REDUCES TENDENCY FOR CARBONYL FORMATION IN THE ABS RESIN DURING LONG TERM HEAT AGING (LTHA). THIS COMPOSITION COMPRISES FOR EXAMPLE, 0.05 TO 1.0 PERCENT OF EACH OF THE FOLLOWING CONSTITUENTS;

(1) DLTDP, (2) 2,6-DI-T-BUTYL-4-METHYLPHENOL, (3) 2,2''-METHYLENEBIS (4-ETHYL-6-T-BUTYLPHENOL), AND (4) AN EPOXY COMPOUND DERIVED FROM SOYBEAN OIL OR BY THE CONDENSATION OF AN ETHYLENE OXIDE WITH A HYDROXYCONTAINING COMPOUND.
