    摘要: Hydrocurable compositions of a hydroxy(polyalkylenecarbonyloxy)alkyleneoxazolidine and a polyfunctional isocyanate are disclosed. The compositions are useful in forming films, paints, coatings, fibers, seamless flooring, coatings, impregnants and adhesives for natural and synthetic materials. The compositions are prepared by treating a hydroxy(polyalkylenecarbonyloxy)alkyleneoxazolidine with a polyfunctional isocyanate or by treating a bisoxazolidine isocyanate prepolymer with a polyfunctional isocyanate.

    摘要: Disclosed are polyfunctional oxazolidine-terminated polyesters of the general formula: ##STR1## WHEREIN Z" is the residue of a polyester having a plurality of terminal ##STR2## groups, the polyester being the condensation product of organic acids and alcohols of the formulae ##STR3## AND R.sup.4 (OH).sub.p, in which o is 2 or 3 and p is 2 to 4, each of o and p preferably being 2;R.sup.1 and R.sup.2 are hydrogen, C.sub.1 -C.sub.4 alkyl, phenyl, benzyl, or collectively C.sub.5 -C.sub.6 cycloalkylene, preferably hydrogen;R.sup.3 is a covalent bond, a C.sub.1 -C.sub.10 residue of an aliphatic or aromatic polycarboxylic acid, preferably C.sub.1 -C.sub.10 alkylidene;R.sup.4 is the residue of a polyol having 2-15 carbon atoms, preferably C.sub.2 -C.sub.10 alkylidene;X and Y are selected from the radicals (--CH.sub.2 --).sub.2 and (--CH.sub.2 --).sub.3, preferably (--CH.sub.2 --).sub.2 ;n is an integer having a value of at least 2, preferably no more than about 8;The acid moieties being present in an amount of from 2 to about 12 units and the alcohol moieties numbering from 1 to about 11, with the proviso that said polyesters terminated with a plurality of oxazolidine groups provide a useable viscosity for coatings in the formulations in which they are used, suitably produced by means of a transesterification reaction between a hydroxy oxazolidine, a polycarboxylic acid ester in which the carboxyl groups are esterified by a C.sub.1 -C.sub.4 alkanol such as methanol, and a polyol. The oxazolidine-terminated polyesters are useful in preparing or formulating moisture-curable mixtures with polyfunctional isocyanates, preferably having two --NCO groups, but compounds having three or more such groups being useful, for coatings, caulks, impregnants, adhesives for textiles, leather, plastics, wood, and metals, and binding agents for pigments, fibers and nonwoven fabrics. The approximate Mw is suitably between 600 and 5000 and the approximate Mn is suitably between 400 and 3000 as determined by gel permeation chromatography.
