Abstract

A polymeric material comprised of (i) at least one random copolymer comprised of ethylene oxide and one or more other alkylene oxide(s) and (ii) at least one non-random polymer comprised of one or more poly(alkylene oxide)s has been discovered. Preferably, it is a polymer alloy. Alkylene oxide homo-polymers or block copolymers may be the non-random polymer. In a related discovery, an adhesive material can be made by suspending (a) particles in (b) a matrix of at least one poly(ethylene oxide) copolymer of ethylene oxide and propylene oxide, or a combination thereof. The handling characteristics may be adjusted for different utilities (e.g., from runny oil to hard wax). Applications include use as adhesive, cohesive, filler, lubricant, surfactant, or any combination thereof. In particular, the hard materials may be used for cleaning or waxing.
