Abstract
Alkylene oxide homopolymer and copolymers are made by polymerizing one or more alkylene oxides in the presence of a catalyst comprising the reaction product of an organometallic compound of the general formula M(R)n, where M is zinc or tin, n is an integer corresponding to the valency of M, and R is a C1 to C5 alkyl group, and an organic compound containing at least two hydroxyl groups and/or mercapto groups, or a hydroxyl group and a mercapto group. The polymerization may be effected in bulk or in a hydrocarbon or ether solvent. Specified alkylene oxides are ethylene, propylene, butylene, and styrene oxides, and butadiene monoxide. Exemplified organometallics are diethyl and diisobutyl zinc, and tetraethyl tin. The Specification contains an extensive list of suitable organic compounds. Exemplified compounds are sucrose, mono- and di-palmitate, ethylene glycol, butandiol, the monopotassium alcoholate of sucrose mono-palmitate, sucrose, glucose, sorbitol, sorbose, diacetone sorbose, pentaerythritol, glycol, polyethylene glycol, polypropylene glycol, polyvinyl alcohol, 2,6-di-(hydroxyethyl) pyridine, tri-(hydroxymethyl)-aminomethane, dimethylsilane diol, methylsilane triol, catechol, resorcinol, hydroquinone, pyrogallol, inositol, dihydroxynaphthol, thioglycol, and alizarine. After polymerization, the catalyst may be decomposed by aqueous methanol. The polymers have intrinsic viscosities of up to 20.ALSO:A polymerization catalyst for alkylene oxides comprises the reaction product of an organometallic compound of the general formula M(R)n wherein M is zinc or tin, n is an integer corresponding to the valency of M, and R is a C1-C5 alkyl group, and an organic compound containing at least two hydroxyl groups and/or mercapto groups or a hydroxyl group and a mercapto group. The organic compounds may be selected from polyhydric alcohols, phenols, thioalcohols and thiophenols, hydroxyalkyl mercaptides, polyalkylene glycols, polyvinyl alcohol, partially hydrolysed polyvinyl acetate, carbohydrates and derivatives thereof, hydroxy nitrogen-containing compounds, primary condensates of phenol and formaldehyde, and hydroxy silicon-containing compounds. The Specification contains an extensive list of these compounds. Exemplified compounds are sucrose mono- and dipalmitate, ethylene glycol, butandiol, the monopotassium alcoholate of sucrose monopalmitate, sucrose, glucose, sorbitol, sorbose, diacetone sorbose, pentaerythritol, glycol, polyethylene glycol, polypropylene glycol, polyvinyl alcohol, 2,6-di-(hydroxyethyl) pyridine, 2,4,6-tri-(hydroxyethyl) pyridine, tri-(hydroxymethyl) aminomethane, dimethylsilane diol, methylsilane triol, catechol, resorcinol, hydroquinone, pyrogallol, inositol, dihydroxynaphthol, thioglycol, and alizarine. Exemplified organometallics are diethyl and diisobutyl zinc, and tetraethyl tin. The catalyst is preferably formed in a hydrocarbon diluent such as benzene.
