Popis: | Dibromochloroacetaldehyde was synthesized in good yield from chloroacetaldehyde diethyl acetal by bromination. It was purified to give a monomer suitable for homo- and copolymerization. Polymerization could be carried out with anionic and cationic initiators; anionic polymerization gave good yields of a crystalline polymer which could be stabilized. Vacuum degradation of the polymer gave the monomer form quantitatively. The Tc of polymerization (1 M) was −40°C. Dibromochloroacetaldehyde copolymerized with chloral and phenyl isocyanate to insoluble and infusible polymer, but was less reactive than chloral. |
