Poly bd® resins are characterized by low volatiles content, low glass transition temperatures, excellent hydrophobicity and a high level of reactive functionality. The facile reaction of Poly bd® resins with curing agents such as di- and polyisocyanates provides an economical route to the preparation of general-purpose polyurethane elastomers. The unique structure of the Poly bd® resins provides properties which surpass typical polyether and polyester polyol based urethane systems, as well as ® conventional, general-purpose rubbers. All grades of Poly bd resins contain unsatur- ® ated double bonds that can be cured or crosslinked, and several grades of Poly bd resin contain epoxide functionality. Some of the outstanding performance characteristics Poly bd® resins provide to products include: Adhesion to a variety of substrates Hydrolytic stability Aqueous resistance to acids and bases Low temperature flexibility Lo
