  • Reactive oligomers
    Patent number: 7074858
    Abstract: The present invention provides novel compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component oligomer possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.
