Functionalized polyesters polycaprolactone

In order to achieve lower gelation doses for saturated linear aliphatic polyesters such as polycaprolactone, certain functional groups including unsaturation can be incorporated. In this regard, and as will be discussed here, e-caprolactone has been copolymerized with a relatively small amount of allyl glycidyl ether. Therefore, the randomly distributed allyl glycidyl ether units(2-6 mole percent) in the synthesized caprolactone-allyl... 

Ester bond-hastd polymers, called polyesters, include several biodegradable and nonbiodegradable polymers such as polyethylene terephthalate (PET), polybutylene terephthalate, polybutylene succinate, polycaprolactone, polylactic acid, polyhydroxyalcanoate and aromatic-aliphatic polyesters. They are derived from starting monomers such as dialcohol, diacid and/or their esters (like methyl esters), and hydroxyl acids that are monomers with both an alcoholic and a carboxylic functional group. All such monomers react to form ester bonds with the release of water (or methanol if the starting monomers are the methylic esters of diacids).
