摘要:
Copolyesters formed from 1,4-butanediol and a dicarboxylic acid mixture of, relative to the polyester, 8-12 mol % of sebacic acid or of an amount equal by weight of a saturated aliphatic dicarboxylic acid having 6 to 36 C atoms, 26-32 mol % of terephthalic acid and 7.5 to 12 mol % of isophthalic acid are hot melt adhesives which are characterized by resistance to ageing even at elevated temperatures, good adhesive strength and a relatively high heat resistance of the bonded areas.
