Hj. Flammersheim et al., THE STEP-GROWTH POLYMERIZATION OF DITHIOLS AND DIISOCYANATES .1. DSC AND SPECTROSCOPIC INVESTIGATIONS REGARDING THE MECHANISM, Thermochimica acta, 229, 1993, pp. 281-287
The polyaddition reaction of diisocyanates and dithiols was investigat
ed by isothermal DSC measurements and by the spectroscopic methods IRS
, UVS and NMR. Using multivariate, non-linear regression, a reaction m
echanism is suggested, which is capable of explaining all the experime
ntal results.
