Abstract: Polyisocyanurate or polyurethane-isocyanurate polymers are made by curing an aromatic polyisocyanate or a mixture of at least one aromatic polyisocyanate and at least one polyol having a hydroxyl equivalent weight of up to 200 in which the isocyanate index is at least 2.00, in the presence of at least one isocyanate trimerization catalyst, to form a polyisocyanurate or polyurethane-isocyanurate polymer having a glass transition temperature of at least 100° C., and then exposing the polyisocyanurate or polyurethane-isocyanurate polymer formed step a) to water under superatmospheric pressure at a temperature of at least 70° C.

Abstract: Solid, non-melting polyurethanes having a glass transition temperature of at least 40° C. and free isocyanate groups are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these polyurethanes will self-bond. The polyurethanes can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These polyurethane adhesives are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.

Abstract: Solid compositions made from or coated with a non-melting organic polymer having a main glass transition temperature of at least 65° C., few if any isocyanate groups and a wet aged glass transition temperature of up to 60° C. are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these compositions will self-bond. The compositions can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These compositions are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.
