    Abstract: This invention relates to the production of hydroxy-terminated polymers in the 2,000-20,000 MW range suitable for use as prepolymers in curing reactions with isocyanates to produce elastomers. The process involves the continuous addition over periods of 25-50 hours of an oxirane (monoepoxide) or a mixture of an oxirane and an oxetane to a reaction mixture, consisting of stoichiometric excesses of oxonium ion-forming catalyst such as BF.sub.3 -etherate and a diol initiator dissolved in an inert solvent. Under these conditions, chain extension of the diol occurs and the formation of cyclic oligomers and other impurities is minimised. The mole ratio of the initiator to catalyst is maintained at above 10:1 to suppress the formation of cationic terminal species on the growing polymer chain.

  • Patent number: 5109075
    Abstract: A copolymer of an olefinically unsaturated monomer and an allylically headed macromolecular monomer ("macromer") of a ring-openable cyclic ether ("CE") is prepared as a comb-shaped graft copolymer of macromer. A wide variety of olefinically unsaturated monomers may be used to form the copolymer. The macromer, having an allylic group near one end and a hydroxyl group at the other, is first produced by cationic ring-opening polymerization of the CE in conjunction with an unsaturated alcohol (propagator) having an allyl double bond. The polymerization to form the graft copolymer proceeds either by free radical polymerization or by metathesis polymerization. The graft copolymer of macromer has a hydrocarbon backbone and pendant chains of polymerized CE, each pendant chain terminating with an OH group.

  • Patent number: 5099075
    Abstract: The present invention relates to a process for removing double metal cyanide complex catalyst residue(s) from polyol(s) which comprises after polyol formation the steps of: (a) contacting the catalyst residue-containing polyol with an effective amount of an oxidant to cause said residue(s) to form insoluble residues that are insoluble in the polyol, and (b) separating the insoluble residues from the polyol. In another aspect, the present invention relates to the oxidant-free polyol produced by the above process.
