Preparation of Molecularly Imprinted Cross-Linked Copolymers by Thermal Degradation of Poly(methacryl-N,N'-diisopropylurea-co-ethylene glycol dimethacrylate)

摘要

Crosslinked porous copolymers of methacryl-isopropykmide with ethylene glycol dimethacrylate, poly(MA-iPrA-co-EDMA), were prepared by thermal degradation of crosslinked copolymers of methacryl-diisopropylurea with ethylene glycol dimethacrylate, pory(MA-DiPrU-co-EDMA), at temperature of 180-250°C in vacuum or under TGA conditions in nitrogen. Nonporous copolymers which represent the model compound of porous copolymers of the same structure were also prepared Both, porous and nonporous model copolymers have almost the same thermal stability as shown by TGA measurements. At the same time the T_g of porous and nonporous model copolymers are different and indicate that nonporous coporymers have higher structural ordering.
