The present invention provides a multi-block copolymer with polyoxyethylene unit in side chain and a polymer electrolyte containing the multi-block copolymer. Since the multi-block copolymer has a number of block of larger than 3, it can completely avoid crystallization and is easier to has phase separation morphology, especially co-continuous phase morphology, and thus has better performance. For the polymer electrolyte, co-continuous phase morphology can be achieved in a wide range of segment A content. The polymer electrolyte of the present invention is thus greatly improved in ionic conductivity and mechanical properties.

Disclosed is a solid phase polymerization method for a high molecular weight aliphatic polyester, wherein the solid phase polymerization of the aliphatic polyester prepolymer is carried out under a gas flow containing a sulfoacid catalyst. While the method has the advantages of a simple process and a low running cost, it can prepare aliphatic polyesters which have a high molecular weight, excellent colour, excellent thermal stability and can be metal-free with a high efficiency. Compared to other polyesters containing a metal, in addition to general applications, metal-free aliphatic polyesters are more suitable for using as a high added value to medical material and packaging material which has direct contact with food.
