  • Patent number: 6924000
    Abstract: An environmentally preferred flock adhesive composition containing low molecular weight prepolymers of isocyanate terminated polyether and/or polyalkadiene polyols is disclosed. The prepolymers are free of residual volatile isocyanate (<1000 ppm) without blocking the isocyanate thereby providing favorable effects on viscosity, cure kinetics, and safety. The flock adhesive composition preferably contains an aromatic nitroso compound an epoxy novolak resin and a catalyst. The adhesive compositions can be made at high solids, with minimal co-solvent, while maintaining low viscosity, which is favorable to environmental regulations aimed at reducing solvent emissions. Furthermore, the solvents can be non-HAP and non-photochemically reactive. The adhesive composition can be utilized for the application of flocking fibers to various elastomer substrates.

    Abstract: Hyperbranched polymers are prepared by a process in which a monomer having the form Ax is reacted with another monomer of the form By, where A and B are functional groups that do not react with themselves, but do react with each other. The process allows synthesis of hyperbranched polymers having a single type of terminal functional group from comonomers, each of which has a single type of functional group. The invention allows greater flexibility in the preparation of a larger variety of different hyperbranched polymers and enables hyperbranched polymers to be prepared at a lower cost as compared with conventional processes using monomers having two types of functional groups that react during polymerization.
