摘要： A polyester composition has a number average molecular weight M.sub.n of between about 500 and about 1000, a weight average molecular weight M.sub.w of between about 600 and about 2000, a polydispersity below about 2, preferably below about 1.8, hydroxyl functionality between 2 and 3, a hydroxyl value of between about 160 and about 260, and an acid number below about 10. Less than about 5% of the OH groups of the polyester are pendent, the rest being terminal. Between about 10 and about 50 wt % of the monomers used to form the polyester composition are anhydrides having the formula: ##STR1## where R.sup.1 is a non-aromatic, saturated or unsaturated hydrocarbon chain having between 6 and 30 carbon atoms, R.sup.2 is hydrogen or a non-aromatic saturated or unsaturated hydrocarbon having between 1 and 8 carbon atoms, and R.sup.1 and R.sup.2 have, in total, between 8 and 30 carbon atoms. The polyester in conjunction with a hydroxyl-reactive curative provides a coating composition.

摘要： A process for polymerizing oxiranes, oxetanes, oxepanes, dioxolanes, trioxanes, and tetrahydrofurans to their respective polymers by contacting them with a selected metal compound is disclosed; and also a process for depolymerizing polytetrahydrofurans to monomeric tetrahydrofurans by contacting the polymer with a selected metal compound at a temperature of about 100.degree. C. to about 250.degree. C. The catalysts may be in solution or part of a heterogeneous solid, and selected organic compounds are used as accelerators in the polymerizations. The polymeric products, some of which are novel, may be used as polyether monomers for further polymerization, as by reaction with isocyanates to produce polyurethanes, and other useful polymers. Some of the polymeric products are relatively high in molecular weight and are suitable for direct use, for instance as spandex fibers.

The polyester composition desirably contains at least 1.6 equivalents of unreacted hydroxy groups or at least 1.6 equivalents of unreacted carboxy groups per mole. The composition contains at least four equivalents of ester links in the main chains of the molecules per mole.The composition of the present invention is obtained by the method of the invention wherein alternating series of reactions are each driven essentially to completion where the final molecule of each reaction provides the only available reaction site for the next alternate monomer reaction. The reactions used are the reaction of an anhydride with a hydroxyl to give an ester and a carboxyl group and the reaction of an oxirane group with a carboxyl to give an ester and a hydroxyl group. To start the alternating reaction sequence either a polyol (to react with anhydride) or a polycarboxylic acid (to react with an oxirane) is used.
