Abstract
The properties of the polyformals of several alicyclic diols were determined. Particularly unusual were the properties of the polyformal of 2,2,4,4-tetramethyl-1,3-cyclobutanediol. The polymer of the 1 : 1 cis/trans diol mixture had a reversible transition in crystalline phase at about 177°C. and a crystalline melting point of 262°C. The polymer was soluble in chloroform and in hot toluene. It was resistant to hydrolysis, particularly alkaline hydrolysis. Physical properties were determined on molded specimens obtained by injection-molding, on films obtained by casting and pressing, and on fibers obtained by melt-spinning.
