Popis: | The composition and structure of siloxane-urethane copolymers obtained by non-equilibrium, low temperature polycondensation, have been investigated by PMR spectroscopy. It is shown that in one stage, non-equilibrium, heterogeneous copoly-condensation, block copolymers are formed, regardless of the method used for the reaction or the rate of the intermonomer. |
