Claim 15:
16. A polyester consisting of two or more structural units (a1), a plurality of structural units (a2), either one or two terminal structural groups (a3), and one or more structural units (a4),, wherein
each G1 is independently (OCnH2n) with n being a number of from 2 to 10,
R1 is a C1-30 alkyl,
p is, based on a molar average, a number of from 1 to 200,
q is, based on a molar average, a number of from 0 to 40,
where

the (OC3H6)— and (OC2H4)-groups of the terminal group (a3) may be arranged blockwise, alternating, periodically and/or statistically,
either of the groups (OC3H6)— and (OC2H4)— can be linked to R1— and —O,
adjacent structural units (a1) are connected by the structural unit (a2), in the case that only one terminal group (a3) is present in the polymer, the other terminal group is selected from the group consisting of OH, OCH3, and G1OH,
both terminal groups may be only linked to a structural unit (a1) or (a4) and wherein structural units (a4) may be indirectly linked to structural units (a1) or other structural units (a4) via the structural units (a2), or directly linked to a terminal group.
