Abstract

In this investigation, the carboxyl group enriched polyurethane (PU) was initially synthesized by solution polymerization and the EX810 was used to link PU and collagen. Proton magnetic resonance (1H-NMR) and Fourier Transfer Infrared Spectra (FTIR) were used to characterize the chemical structure of PU and the epoxy grafted PU (epoxy-PU). The n-order reaction rate and Arrhenius equation were used to determine the apparent reaction order and apparent activation energy. Our results demonstrated that the reaction between EX810 and PU is an 1.31 apparent reaction order with apparent activation energy of 22.9 kcal/mol. The reaction between epoxy-PU and collagen is an 1.9 apparent reaction order with apparent activation energy of 15.24 kcal/mol.
