STYRYL TERMINATED MACROMOLECULAR MONOMERS OF POLYETHERS ABSTRACT OF THE DISCLOSURE A cationic ring-opening polymerization of a cylic ether ("CE") in conjunction with an unsaturated alcohol (propagator) having a styryl or substituted styryl group, produces a polyether macromer having the styryl group near one end and a hydroxyl group at the other. The polymerization proceeds by polyaddition of the CE to the OH group which is the propagating species. The CE is an alkylene oxide or an aliphatic or aromatic gly- cidyl ether; the propagator is a primary or secondary alcohol. The catalyst is a Friedel-Crafts acid, strong protic organic or inorganic acid, oxonium salt, or the like. Plural cyclic ethers may be (a) sequentially polymerized to form macromer block copolyethers, or, (b) polymerized randomly to form macromer copolyether co- polymers. The cationically ring-opened macromer formed always contains a trace of a cyclic oligomer of the CE. The macromer formed may be homopolymerized to yield a homopolymer of the macromer with pendant chains of poly- merized CE; or the macromer may be copolymerized with a wide variety of olefinically unsaturated monomers to form a copolymer of macromer.
