Abstract:

A method is described, using the title spectroscopy and a specially designed stretching app., to det. short-time spectroscopic and mech. data simultaneously during deformation and relaxation of urethane rubbers. The data obtained from adipic acid-1,4-butanediol-diphenylmethane 4,4'-diisocyanate-ethylene glycol copolymer [27083-55-2] rubbers of 3 different hard- and soft-segment contents at ambient temp. were discussed in terms of the segmental orientation induced during uniaxial elongation and recovery.
