Diacetylene-Containing Polymers V. Synthesis and Characterization of High Molecular Weight Diacetylene Containing Thermoplastic Polyesters: Poly(octa-3,5-diynylene succinate), Poly(octa-3,5-diynylene adipate), and Poly(octa-3,5-diynylene sebacate)

ABSTRACT:  New diacetylene-containing polymers: poly(octa-3,5-diynylene succinate), poly(octa-3,5-diynylene adipate, and poly(octa-3,5-diynylene sebacate) were synthesized by oxidative polycoupling of the corresponding bis-acetylenes to give high molecular weight thermoplastic film and fiber forming polymers. The polymers were thermo- and photosensitive and underwent topochemical cross-polymerization either on irradiation or heating in crystalline state to give polydiacetylene network. They can be stretched at room temperature to give strong, transparent anisotropic photosensitive materials.
