Ss. Bukalov et al., COMPLEX THERMOCHROMIC PHASE-TRANSITIONS IN 3 POLYDIALKYLSILANES WITH AN OXYGEN-ATOM IN THE SIDE-CHAIN, Mendeleev communications, (4), 1996, pp. 135-137
Temperature investigations of the UV and Raman spectra of three polydi
alkylsilanes with an oxygen atom in the side chain have shown that all
polymers studied undergo a thermochromic phase transition in the inte
rval from +20 to -70 degrees C which is not abrupt but is kinetically
limited; this transition is of the order-disorder type and is related
to a change in the conformation of the polymer main chain from a disor
dered one to all-trans.
