Polyesterpolyol derivative and a poly(urethane)ureamide obtained therefrom |
| abstract |
A polymer comprising a poly(urethane)ureamide is prepared by a reaction of a polyisocyanate and a polyesterpolyol derivative of the formula [I] <IMAGE> [I] wherein A is an n-valaent radical obtained by removal of terminal hydrogen atoms from an n-valaent polyester-polyol having a molecular weight of 400 to 10,000 and containing <IMAGE> group in the main chain, n is an integer of 2</=n</=4, x is an average value and a number of 0</=x</=(n-1), -NH- group of <IMAGE> in the main chain forms an amido group connected with a carbonyl group of an aminobenzoic acid and/or a carbonyl group of a polybasic acid component of the polyesterpolyol and, -CO- group of <IMAGE> in the main chain forms an ester group or amido group. The polymer has higher heat resistance and greater mechanical strength as compared to corresponding polyester-urethanes. |
