摘要:
The invention relates to highly functionalized polyurethanes which are synthesized from molecules containing the functional groups A(B).sub.n, where A is an NCO group or a group reactive with an NCO group, B is an NCO group or a group reactive with an NCO group, A is reactive with B and n is a positive number and is at least equal to 2.
