Our future work includes the synthesis of highly regular segmented copolymers via step polymerization of the telechelomer and investigating their structure-property relationships. [Pg.163]

For equilibration processes, one must synthesize both oligomers and what are termed dimers, or disiloxanes. Our primary interest is in the utilization of these functional oligomers for the synthesis of both linear block or segmented copolymers, and also surface modified, oughened networks such as the epoxy and imide systems (3-27). The generalized structure of the oligomers of interest is shown in Scheme 1. [Pg.181]

The earlier sections of this review have attempted to review the synthesis and characterization of the segmented copolymer materials as well as to highlight fundamental efforts related to a number of structure-property relationships. Polyimide-siloxane copolymers are high performance materials that have been driven by applications frequently identified with aerospace. However, this section will also include surface phenomena which are critical for certain electronic applications and high performance blends utilizing imide-siloxane copolymers. [Pg.89]
