Abstract
The present invention refers to a polyesterpolyol which is obtained by reaction of at least one diol with at least one primary hydroxy group and at least one secondary hydroxy group with a saturated aliphatic dicarboxylic acid comprising a carbon chain of at least 12 carbon atoms. The invention further relates to an adhesive composition containing the polyesterpolyol, in particular a polyurethane adhesive composition.
Claims18
A crystalline polyesterpolyol that is the reaction product of a reaction mixture comprising:
- a) a diol selected from the group consisting of 1,2-propane diol, 1,3-butane diol, and 1,4-pentane diol;
- b) a saturated aliphatic dicarboxylic acid having a carbon chain of 12 carbon atoms or 14 carbon atoms, wherein the carbon chain is terminated at each end with a carboxylic acid group;
- and
- c) at least one other diol and/or at least one additional dicarboxylic acid,
- wherein the crystalline polyesterpolyol is liquid at ambient temperature and exhibits defined polymorphic crystallization peaks below 50° C., determined by DSC with a heating rate of 10K/min.
A crystalline polyesterpolyol that is the reaction product of a reaction mixture comprising:
- a) a diol selected from the group consisting of 1,2-propane diol, 1,3-butane diol, and 1,4-pentane diol;
- and
- b) a saturated aliphatic dicarboxylic acid selected from the group consisting of 1,16-hexaadecanedioic acid and 1,18-octadecanedioic acid,
- wherein the crystalline polyesterpolyol is liquid at ambient temperature and exhibits defined polymorphic crystallization peaks below 50° C., determined by DSC with a heating rate of 10K/min.
