Problems solved by technology

The prior art (CN201480071441.9) provides a preparation method of biodegradable polyester resin, which mainly prepares a kind of effective biodegradable polyester resin through dicarboxylic acid, diol, catalyst and deactivator that can reduce catalyst activity. Degradable polyester resin materials, but lack of related modification or addition of rigid monomers, can not effectively improve the toughness and mechanical properties of degradable polyester resin materials, greatly reducing the application field of polyester materials and environment
