A method for producing a multi-arm type polyethylene glycol derivative, which includes carrying out the following in order: Step (A): protecting an even number of hydroxyl groups, while leaving only the hydroxyl group at the 1-position of a polyhydric alcohol having an odd number of hydroxyl groups, other than the hydroxyl group at the 1-position by cyclic benzylidene acetalization, Step (B): linking two molecules of the compound obtained in step (A) to a compound for introducing a specific linker by etherification reaction, Step (C): deprotecting the cyclic benzylidene acetal structure at the terminal of the compound obtained in step (B), Step (D): polymerizing 3 to 600 mol of ethylene oxide to each hydroxyl group of the compound obtained in step (C) to obtain a multi-arm type polyethylene glycol derivative, and Step (E): functionalizing the hydroxyl group at the terminal of the multi-arm type polyethylene glycol derivative obtained in step (D).

A process of forming a lactide copolymer includes forming a dimethylidene lactide molecule from an L-lactide molecule. The process also includes forming a functionalized lactide monomer from the dimethylidene lactide molecule. The process includes forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer. The process further includes polymerizing the mixture to form a lactide copolymer.

Disclosed herein is a polyalkylene oxide ester polymer with a weight average molecular weight Mw in the range of from 500 to 50,000 g/mol and a polydispersity PD in the range of from 2 to 6, including 10 to 560 ether groups and 2 to 51 ester groups that are interconnected with alkylene groups, which are significantly more biodegradable than conventional polyalkylene oxide polymers. Further disclosed herein are a method of preparing a polyalkylene oxide ester polymer and a method of using the polyalkylene oxide ester polymer.
