    Abstract: The invention relates to a polyester comprising two or more of the structural units (a1), one or more of the structural units (a2) and either one or two of the terminal groups (a3) (a1) (a2) (a3) wherein G 1 is one or more of (OC n H 2n ) with n being a number of from 2 to 10, preferably from 2 to 6 and more preferably (OC 2 H 4 ), (OC 3 H 6 ), (OC 4 H 8 ) or (OC 6 H 12 ), R 1 is a C 1-30 alkyl, preferably C 1-4 alkyl and more preferably methyl, p is, based on a molar average, a number of at least 60, preferably from 70 to 200 and more preferably from 90 to 130, q is, based on a molar average, a number of from 0 to 40, preferably from 0 to 30, more preferably from 0 to 20, and most preferably from 0 to 10, where the (OC 3 H 6 )- and (OC 2 H 4 )-groups of the terminal group (a3) may be arranged blockwise, alternating, periodically and/or statistically, preferably blockwise and/or statistically, either of the groups (O-C 3 H 6 )- and (O-C 2 -H 4 )- of the terminal group (a3) can be linked to R 1 - and Ο-, adjacent structural units (a1) are connected by the structural unit (a2), in the case that only one terminal group (a3) is present in the polyester, the other terminal group is selected from the group consisting of OH, OCH 3 , and G 1 OH, and both terminal groups are linked to acyl groups derived from a dicarboxylic acid, preferably to structural units (a1).
