Abstract: A polyester-containing hot-melt adhesive for the bonding of materials, based on a phthalic acid, an aliphatic C6 to C12 dicarboxylic acid, and a glycol with from two to 10 carbon atoms in the radical between the two OH groups, comprising A. ABOUT 20 TO 95 WT. PERCENT OF A POLYESTER WHEREIN ABOUT 5 TO 20 MOLE PERCENT OF THE DICARBOXYLIC ACID COMPONENT COMPRISES AN ALIPHATIC DICARBOXYLIC ACID, THE POLYESTER HAVING A MELTING POINT OF OVER ABOUT 150* C, and B. ABOUT 5 TO 80 WT. PERCENT OF A POLYESTER WHEREIN ABOUT 25 TO 35 MOLE PERCENT OF THE DICARBOXYLIC ACID COMPONENT COMPRISES AN ALIPHATIC DICARBOXYLIC ACID, THE POLYESTER HAVING A MELTING POINT BETWEEN ABOUT 50 AND 150* C.

Abstract translation: 一种含有聚酯的热熔粘合剂，用于粘合基于邻苯二甲酸，脂族C 6至C 12二羧酸的物质和在两个OH基团之间的基团中具有2至10个碳原子的二醇，其包含A. 约20至95 WT。 聚酯的百分比约为5至20％的二羧酸成分含有一种二硫代羧酸，该聚酯具有超过150℃的熔点以及B约5至80℃。 聚酯的百分之二十五至三十五分之二十六烷酸含量的二聚酸组分包含二氢二羧酸，该聚酯具有约50至150℃之间的熔点。
