| titleOfInvention | Allyl terminated macromolecular monomers of polyethers |
| abstract | ABSTRACT OF THE DISCLOSURE A cationic ring-opening polymerization of a cyclic ether ("CE") in conjunction with an unsaturated alcohol (propagator) having an allyl double bond, produces a polyether macromer having an allylic group near one end and a hydroxyl group at the other; and prior problems associated with the use of olefinic monomers to produce such macromers are avoided; the macromers may be employed to produce a variety of graft and comb copoly-mers including liquid polymers which are beneficial as dispersants in polymerizations by lowering the viscosity of the reaction mass; in particular the macromers may be quaternized to yield anti-statics, fiber softeners, excipients for drugs and biomimetic drugs; the cationic ring-opening 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 glycidyl ether; the propagator is a primary or secondary alcohol which, if cyclic may have a single internal double bond in one ring; the catalyst is a Friedel-Crafts acid, strong protic organic or inorganic acid, oxonium salt, or the like; the macromer formed may be homopolymerized to yield a polyvinyl homomacro-mer with pendant chains of polymerized CE; or the CE may be copolymerized with a wide variety of olefini-cally unsaturated monomers to form a macromer copolymer; or, plural cyclic ethers may be (a) sequentially poly-merized 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. |
