23 Jul Unsaturated aliphatic polyester as well as preparation method and application thereof
Abstract
The invention relates to unsaturated aliphatic polyester. The polyester is formed by linearly and randomly arraying structure units shown in the chemical formula (I) and structure units shown in the chemical formula (II) at a molar ratio of 3:7-7:3, wherein the number-average molecular weight is 5,000-12,000, and the dispersibility index is 1.21-1.80; the unsaturated aliphatic polyester is obtained by ring-opening polyaddition of GMA (glycidyl methacrylate), n-butyl glycidyl ether and succinic anhydride. The unsaturated aliphatic polyester provided by the invention can be used for preparing a tissue engineering scaffold; the scaffold has better elasticity modulus and swelling property and is low in cytotoxicity, good in biocompatibility and high in cellular affinity.
