Systhesis and Characterization of High Temperature and Humidity Resistant Polyester
In this paper,a series of polyester composed of isophthalic acid,phthalic anhydride,sebacic acid,ethylene glycol,and neopentyl glycol were synthesized,used tetrabutyl titanate as a catalyst.The effect of different alcohol-acid ratios on acid value was investigated,polyester was characterized by 1H-NMR and FT-IR,acid value,types of polyesters with different polybasic acids and polyols,hydrolysis-resistant agents,and epoxy resins on adhesives were discussed resistant to the effects of high temperature and humidity.
