| Abstract: | On-line following of reaction injection molding(RIM)of poly(urethane urea) s,which finished within several seconds, has been carried out by a 5SX FTIR. A mini-RIM machine and a single reflector for infrared sampling which were made in our laboratory were used successfully in the experiments. There is a very strong tendency of phase separation during RIM polymerization of poly(urethane urea)s.Although there was not a marked effect of dibutyltin dilaurate concentration on overall rate of polymerization, the effect was intense on phase separation and hydrogen bonding of RIM poly(urethane urea)s. |
