Latest Patents

Yajun Zhao holds a patent titled "Method for synthesizing aliphatic polyester block copolymer regulated by carbon monoxide." This innovative method employs an organic cobalt metal complex as a convertible catalyst. The synthesis process begins with regulating an anionic ring-opening copolymerization reaction between an aliphatic acid anhydride and an epoxy compound. The introduction of carbon monoxide serves as a conversion agent, facilitating the formation of a catalyst with a new catalytic active site. Following this, a vinyl monomer is regulated to undergo active free radical polymerization, resulting in an aliphatic polyester block copolymer featuring a controllable structure. This synthesis method creatively combines two controllable polymerization reactions, completed in a 'one-pot' reaction.
