| titleOfInvention | Modified poly(alkylene carbonate) polyahls |
| abstract | Modified poly(alkylene carbonate) polyahls comprising the residue of at least one polyahl, at least one modifier, poly(alkyleneoxy) units, poly(alkylene carbonate) units, and a plurality of active hydrogen end groups are disclosed. The modified polyahls have an average molecular weight higher than any known polyahls containing at least the same weight percent modifier and the same poly(alkyleneoxy) and poly(alkylene carbonate) residues. Also disclosed are isocyanate-functional prepolymer compositions of these modified poly(alkylene carbonate) polyahls, which contain the residue of at least one modified poly(alkylene carbonate) polyahl of this invention and excess organic polyisocyanate units. Urethane/urea polymers formed by the reactions of the isocyanate-functional prepolymers with polyahls are also disclosed. Also disclosed are urethane/urea polymers comprising the residue of at least one modified poly(alkylene carbonate) polyahl of this invention, the residue of a polyisocyanate and the residue of at least one other polyahl selected from the group consisting of polyamines and polyfunctional hydroxyl compounds. The novel compositions of this invention are useful in urethane/urea polymer applications such as foams, elastomers, plastics, adhesives, coatings and the like. |
