SATURATED COPOLYESTER CONSISTING OF TEREPHTHALIC ACID, ISOTEREPHTHALIC ACID AND ALIPHATIC DIOL AND MELT ADHESIVE COMPOSED OF SAID COPOLYESTER

摘要

Linear saturated copolyesters of terephthalic acid, isophthalic acid, butanediol, and one or more aliphatic diols having at least 13 carbon atoms used as adhesives for the formation of wash-resistant bonds especially for temperature-sensitive materials. Preferably, the melting points of these adhesive compositions are from 50 DEG to 170 DEG C. and their relative viscosities, measured as 1% solutions in meta-cresol at 20 DEG C., are 1.40 to 1.80.
