Abstract
The isocyanate polyoxyalkylenes having the formula: EQU OCN--(AO).sub.x --(BO).sub.y --(CO).sub.z --DE I. wherein E is --NCO or an amino group; A, C and D represent lower alkylene of 2 to 4 carbon atoms; B is alkylene of 2 to 8 carbon atoms; y and z are each integers having a value of 0 to 50 and x is an integer having a value of from 2 to 50, and intermixtures of said polyoxyalkylenes. The above compounds display a wide variety of uses, namely for the control of fungi and bacteria or for the prevention of such infestation. They are also useful dielectric constant depressors for polymeric substances, e.g. polyvinylchloride, polyvinylidene halides, etc., extenders for solids in latices and anti-static agents.
