Studies on the Influence of Soft-segment Structure on the Properties of Polyurethane Adhesive

Abstract

Abstract: Two series of polyesters were synthesized from adipic acid(AA), dimethyl terephthalate (DMT), isophthalic acid (IPA), phthalic anhydride (PA), with ethylene glycol (EG),butylenediol-1, 4 (1, 4-BDO), propanediol-1, 2 (1, 2-PDO), hexanediol-1, 6 (1, 6-HDO) and diethylene glycol(DEG) respectively by using melt-polycondensation method in the presence of H,PO₄, SnCl₂.2H₂O, (这里有图片,19970536-807-1.gif), as catalyst respectively.The technological conditions of the polyesters synthesized were studied.This polyesters react separately with diphenylmethane diisocyanat (MDI) by solution polymerization to afford two series of linear block polyurethane adhesives.The crystallinity and the melting point of the polyesters and polyurethanes were determined by means of X-ray diffraction (WAXD), differential scanning calorimetry (DSC)-The relationship between structure and properties of the Polyesters, expecially the influence of the polyesters type on adhesion behavior of the corresponding tl1e polyurethanes were discussed.

Key words: Polyester, Polyurethane, Adhesive, Crystallinity, Relationship between structure and properties
