Abstract

Substantially linear polyurethane resins have the formula <FORM:1012929/C3/1> wherein each R is an alkyl radical containing from 1 to 8 carbon atoms, R1 is a divalent organic radical containing at least two carbon atoms in which both terminal atoms are carbon, R11 in each occurrence is hydrogen or hydrocarbon radicals which in combination with R may form a ring, and is an integer from 10 to 2000. The polymers are prepared (a) by reacting an organic di-isocyanate with a cyclobutanediol of the formula <FORM:1012929/C3/2> or (b) by reacting a diamine with a cyclobutanediol bischloroformate of the formula <FORM:1012929/C3/3> in the presence of an acid binding agent. In process (a) inert organic solvents and catalysts such as tin tetrachloride, organic compounds of tin and dibutylzinc may be used. Either the cis- or the trans-form of the cyclobutanediol or mixtures of the two may be used. In process (b) the acid binding agent may be excess amine or an aqueous solution of an alkali metal hydroxide or carbonate. If an aqueous acid-binding agent is used an inert, water-immiscible, organic solvent may be added to give an interfacial reaction system. The products are useful as fibres and films, moulding and coating compositions, interlayers in safety glass and in the production of foams when the bulk polymer may be blown with carbon dioxide.
