Beschreibung
Zusammenfassung:	The present invention relates to an unsaturated polycarbonate diol (A) comprising terminal hydroxyl groups, at least one repeating unit of formula (Ia) and at least one repeating unit selected from units of formula (Ib) and units of formula (II); the unsaturated polycarbonate diol (A) comprising at least one unsaturated carbon-carbon bond; and to a method for preparing such an unsaturated polycarbonate diol (A), wherein in the formulas, R^1a is selected from the group consisting of a C_2-C_20 acyclic alkylene group, a C_2-C_20 ether group and a C_3-C_20 ester group, R^1b represents a C_2-C_20 acyclic alkenylene group, and R^2 represents a C_2-C_20 acyclic alkenylene group.
