Thiodiethanol based polyurethane elastomers having improved dynamic properties and method for production thereof

摘要

A method for the preparation of a polyetherthioether copolymer glycol represented by the formula: ##EQU1## wherein the mole ratio x/y is in the range of about 45:55 to 60:40, respectively. More specifically, a method for the preparation of a copolymer of thiodiethanol and 1,4- butanediol wherein the mole ratio x/y is about 50:50. Also, the copolymers produced thereby and polyurethane elastomers produced therefrom, particularly those produced from the 50:50 copolymer, and to their use in solid tires having improved dynamic mechanical properties.
