The polycarbonate polyols(PCD) obtained by ring-opening polymerization of a general cyclic monomer tokidoki hello kitty blind box is mostly a linear flexible structure, which is used as a raw material to synthesize polyurethanes, and it is difficult to simultaneously ensure good thermal-mechanical properties and weather resistance due to insufficient rigidity of the main chain.However, PCD based on ring-opening polymerization of cyclohexene carbonate (CHC), endowing with polyurethanes good mechanical properties, weather ability and biological stability because of the rigid structure of six-membered aliphatic rings in the main chain.Therefore, in this paper, the method and principle of preparing new polycarbonate polyols based on ring-opening polymerization of cyclohexene carbonate (CHC) are introduced.

And the problems and countermeasures in its development and its application in la rams crop top polyurethane materials are discussed.
