Abstract

Traditionally o-phthalaldehyde (OPA) has to be homopolymerized or copolymerized with other monomers at low temperature due to its very low ceiling temperature (Tc= -36 °C). In the presence of a Lewis acid such as triethylborane (TEB) the anionic copolymerization of OPA with various epoxides including ethylene oxide, propylene oxide, 1-butene oxide, 1-octene oxide, allyl glycidyl ether, phenyl glycidyl ether, and styrene oxide could be successfully carried out under ambient conditions, resulting in the formation of a host of polyacetals. The role and effect of TEB, its amount, and also the feeding ratio of OPA to epoxides during their copolymerizations were respectively investigated. The successful "living" OPA/epoxides copolymerization was further extended to the synthesis of polyether-b-polyacetal block copolymers with different structure and properties.
