Abstract

In this paper the preparation and characterization of polymers of t-butyl ethylene oxide and styrene oxide are described. Mixtures of water and zinc diethyl, having mole ratios approaching unity, were used as catalysts, and dioxan was used as solvent. The poly( t-butyl ethylene oxide) was highly crystalline and had narrow distributions of both molecular weights and degrees of stereoregularity. The poly(styrene oxide) was slightly crystalline, had a wide molecular weight distribution, and contained molecules of widely different degrees of stereoregularity.
