- W2016707851 abstract "Ethylene oxide is polymerized by diphenylzinc to give polymers with viscosity-average molecular weights of up to 3 × 106. Similar polymers are formed when phenylzinc t-butoxide is used as catalyst, but the reaction is faster; the viscosity-average molecular weight of the product increases in parallel with the degree of conversion of the monomer, and there is a broad distribution of molecular weights. Zinc t-butoxide, which is insoluble, is more active than either of the above systems, and readily gives high yields of poly(ethylene oxide) with viscosity-average molecular weights of up to 9 × 106. Solvents such as cyclohexane and benzene have little effect on the polymerization, but t-butyl alcohol markedly reduces the rate, and gives a product of comparatively low molecular weight. Propylene oxide is polymerized by zinc t-butoxide much less rapidly than ethylene oxide, and the product has a lower degree of polymerization; approximately 12 per cent is ‘crystalline’. The proportion of ‘crystalline’ material is somewhat decreased, but its melting point is raised, when tetrahydropyran is used as solvent." @default.
