## Abstract Two unsaturated polyesters (UPs), PME and PMPE, were synthesized by condensation polymerization, and another UP, BPMPE, was prepared from PMPE by blocking of its carboxyl and hydroxyl end groups. Optically transparent UPβsilica nanocomposites were prepared by a solβgel process of alkoxy
