摘要： PURPOSE: A terephthalic acid-based copolyester useful for adhesives, paints or moldings, containing 1,9-nonanediol as a comonomer.
CONSTITUTION: A copolyester wherein about 80W100mol% of the dicarboxylic acid component is terephthalic acid and 5W95mol% of the glycol component is 1,9-nonanediol [intrinsic viscosity of about 0.2W1.5dl/g (about 0.6W1.2dl/g for adhesive), m.p. of about 240W90°C, a second-order transition point of about 60W0°C]. As glycol components other than 1,9-nonanediol, at least one selected from among a 2W6C polymethylene glycol, cyclohexanedimethanol, a polyoxyalkylene glycol (wherein the alkylene group is ethylene, propylene or tetramethylene) of a MW ≤ 2,000 and a bisphenol oxyalkylene ether glycol (derivative) is used.

摘要： PURPOSE:To produce a polyurethane showing no tendency toward crystallization and excellent in hydrolysis resistance, light fastness, mechanical properties, oil resistance, abrasion resistance, and low-temperature resistance, by reacting a specified polyol with a polyisocyanate. CONSTITUTION:A polyol having a group of the formula in the molecule, average MW of 300-10,000, [e.g., poly(beta-methyl-delta-valerolactone)-polyol] is mixed with an active hydrogen atom-containing low-MW compound (e.g., ethylene glcyol). After preheating the mixture to 40-100 deg.C, a polyioscyanate (e.g., 2,4-tolylene diisocyanate) is added in such an amount that the ratio of the number of the active hydrogen atoms of these compounds to that of the NCO groups is 1:1, and the resulting mixture is agitated vigorously for a short time and allowed to stand at 50-150 deg.C.
