摘要： A hydrophilic, flexible, open cell polyurethane-poly(N-vinyl lactam) interpolymer foam is obtained from the process which comprises reacting under interpolymer and foam-forming conditions (a) a substantially linear isocyanate-capped polyether polyol prepolymer having an average reactive functionality of less that about 2.0 with (b) a poly(N-vinyl lactam) and (c) a foam-forming amount of water in the presence of (d) a cell formation-regulating amount of surface active agent. The foams exhibit unexpectedly higher levels of absorptivity for aqueous fluids compared to those of known crosslinked foams. The foams herein are especially useful for the manufacture of a variety of dental and biomedical products including surgical bandages and dressings, laparotomy sponges, medicament carriers, and the like, where the capability for absorbing body fluids is an important performance criterion.
