摘要：
A process for the preparation of a crosslinked polyester which comprises the reaction of a diol or a mixture of diols and a diacid, a mixture of diacids or their diesters and a polyhydric alcohol monomer to provide a polyhydroxy functional polyester resin precursor, and subsequently reacting said polyhydroxy functional polyester precursor resin with a dianhydride or diepoxy functional crosslinking component.
