ADHESION PROMOTER BASED ON POLYVINYL CHLORIDE OR COPOLYMER OF VINYL CHLORIDE WITH VINYL ACETATE AND PLASTISOL BASED ON POLYVINYL CHLORIDE OR COPOLYMER OF VINYL CHLORIDE WITH VINYL ACETATE Russian patent published in 2002 - IPC

FIELD: chemistry of polymers. SUBSTANCE: invention relates to the field of synthesis of adhesion promoters based on polyethyleneamine. Adhesion promoter is a product of interaction of polyethyleneamine and epoxy diane resin synthesized in their equivalent ratio = (7.4-12.4) : 1, amine number 600-806 mg of KOH/g and viscosity 103-300 Pa x s. Plastisol based on polyvinyl chloride or copolymer of vinyl chloride with vinyl acetate (100 m. p. p.) comprises phthalic acid ester as a plasticizer or its mixture with dioctyladipinate, dioctylsebacate or with plasticizer of mark sort "Edos" (85-100 m. p. p.), lead-containing stabilizing agent (3-7 m. p. p.), calcium carbonate (45-150 m. p. p.), calcium oxide (5-25 m. p. p.), phenolformaldehyde resin of mark sort SF 342A (5-25 m. p. p.) and the above indicated adhesion promoter (0.8-5.6 m. p. p.). Adhesion promoters are used for preparing polyvinyl chloride plastisols and to composites of adhesion polyvinyl chloride plastisols used as glues for oily, fuel, air filters in cars, for sealing and protective covers of metallic surfaces. EFFECT: enhanced adhesion strength and thermostability of plastisol. 2 cl, 3 tbl
