STABILIZED HALOGEN-CONTAINING RESIN COMPOSITION

摘要: PURPOSE:To obtain the titled compsn. which is stabilized against heat and has an excellent discoloration resistance at initial latter stage, by adding a lead stabilizer together with boron compd. derived from esterification reaction of polyhydric alcohol fatty acid boric acid, to halogen- contg. resin. CONSTITUTION:In stabilizing halogen-contg. resin stabilizer, added. When org. phosphite used compd., having further improved stages can be obtd. Examples stabilizers are stearate, dibasic phosphite, salicylate, etc. compds. those formulas I , IIand III, wherein R1 residue partial resulting removal hydroxyl group alcohol; R2, R3, R4 each H or mono- phenol where one removed.
