Abstract: A polyurethane urea fiber or film is made having high elongation, low modulus, low hysteresis loss, and excellent clastic recovery. The clastic polyurethane clastic fiber or film is formed from a copolymer glycol, a diisocyanate, a chain extender and optionally a chain terminator. The hard segment content of the polyurethane fibers is in the range of 8.0-13.0% by weight.

Abstract: Process for the removal of volatile compounds from a tackifier comprising a resin with repeating units of formula I wherein R1 is a linear or branched alkylen group with 1 to 10 carbon atoms and R2 is a linear or branched, saturated or unsaturated N aliphatic hydrocarbon group with up to 20 carbon atoms, and optionally a plasticizer, wherein the tackifier is passed through at least one evaporator as film and the volatile compounds are removed from the film.
