Segmented or block poly(hydroxy ether-siloxane) copolymers that are both chemically cross-linked and microphase separated have been synthesized. In this work, the molecular weight of the siloxane block lengths varied from 900 to 12400g/mol, and the hydroxy ether block lengths varied from 340 to 3700g/mol. Calorimetrie, dynamic mechanical, and small-angle X-ray scattering measurements showed that higher block length oligomers gave networks with a more well-defined two-phase morphology. The mechanical behavior of the networks depended on the continuous phase with ultimate elongations ranging from 50 to 180% and moduli ranging from 1.0 to 600 MPa. © 1988, American Chemical Society.
