Novel [ABm]n segmented copolymers with PDMS as soft segments were synthesized by condensation reaction.The product thus obtained was characterized by IR.Spectroscopy
viscosity and DMA.The results indicate that polycondensation took place intermolecularly as well intramolecularly.Depending the PDMS and rigid segments molecular weight and content
m is in the range from 1 to 6.AB m n segmented copolymers exhibit microphase separation
and partial compatibility between rigid and soft segments.The Tg of rigid segment's phase is dependent on the value ofm.The modulus of these materials is higher than that of [AB]n segmented copolymers.
