Latest Patents
Zheng's latest patents include innovative formulations of acetal copolymers. One of his patents focuses on acetal copolymers with backbone epoxide functional groups. These copolymers are created by copolymerizing trioxane with 5,6-epoxy-1,3-dioxepane. The presence of epoxide groups in the polymer chain provides highly reactive functional sites for further modifications. This innovation results in copolymers that exhibit enhanced toughness and thermal stability. Additionally, the backbone epoxide groups can be aminated through a one-step hydrolysis-amination process.
Another significant patent involves novel polyacetal copolymers of trioxane and trimethylolpropane formal. This invention utilizes cationic copolymerization of trioxane and trimethylolpropane formal or its ester derivatives. The resulting acetal copolymers possess pendant functional groups, which may include hydroxyl or ester moieties. These functional groups are protected during copolymerization, allowing them to serve as reactive sites for the synthesis of block copolymers or for chemically binding modifiers to the acetal copolymer backbone.
