Abstract: A reactive hot melt adhesive has a glass transition temperature of from 45° C. to 100° C. The reactive hot melt adhesive includes the reaction product of: an isocyanate component and an isocyanate reactive component chosen from a polyester, a polyether, and combinations thereof. The isocyanate component and the isocyanate reactive component react in the presence of a styrene acrylic resin that is free of hydroxyl functionality and that is the reaction product of 60 to 80 wt % of one or more monomers chosen from C1 to C20 alkyl acrylates and methacrylates and 20 to 40 wt % of one or more monomers chosen from vinylaromatics having a vinyl moiety having 2 or 3 carbon atoms.

Abstract: Polyurethane foams are made and attached to a substrate having an open cavity, but reacting prepolymer and polyol components in the presence of certain carbamate blowing agents. This process allows for very fast curing, good quality, adherent foamy to be produced on, for example, vehicle parts and assemblies, for acoustical or vibration dampening and for structural reinforcement.

Abstract: Foam-in-place, one component polyurethane compositions are useful to produce foams that adhere to various substrates such as certain vehicle parts and assemblies. The polyurethane composition contains a heat-activated blowing agent. The composition is based on a polyurethane resin that is expandable. The resin is a heat-softenable material, or a low molecular weight material that engages in further curing during the heat expansion step.

Abstract: The present invention is directed to a novel method of preparing a polymerizate, which includes the step of polymerizing a two-component composition, which includes: a first component containing at least one polycyanate reactant having at least two functional groups selected from isocyanate, isothiocyanate and combinations thereof, the polycyanate reactant being the reaction product of: a polythiol monomer having at least two thiol groups; and a polycyanate monomer having at least two functional groups selected from isocyanate, isothiocyanate and combinations thereof; and a second component containing at least one polyamine reactant having at least two functional groups selected from primary amine, secondary amine and combinations thereof. The molar equivalent ratio of (NCO+NCS) groups from the first component to (—NH2+—NH—) groups from the second component is from 0.5 to 100. The present invention is also directed to polymerizates prepared according to the method of the present invention.

Abstract: Rigid polyurethane foams are described. The foams are made using a prepolymer that is the reaction product of at least one polyisocyanate component, at least one hydroxy-functional acrylate component, and at least one polyol component. The prepolymer is then reacted at specified volume ratios and isocyanate indices with at least one polyol component that includes at least one polyol that is a biopolymer, including but not limited to castor oil, soybean oil, and the like. The foam is made in the presence of at least one blowing agent and at least one catalyst.

Abstract: Described are photochromic organic resin compositions and the impact resistant polymerizates and coating compositions made therefrom. The organic resin composition comprises the reaction product of at least one polyol having greater than 1.0 hydroxyl groups; at least one polyisocyanate having greater than 1.0 isocyanato groups; and at least one polyamine curing agent having greater than 1.0 amino groups. The polymerizates are made photochromic either by the addition of organic photochromic compounds to the reactants used to form the polymerizate or by methods that imbibe or transfer the photochromic compounds into the polymerizate. Optically clear photochromic and impact resistant articles such as ophthalmic lenses and articles having photochromic coatings prepared from the photochromic organic resin compositions are also described.

Abstract: A composition comprising a vinyl acetate acrylic copolymer or a carboxylated acrylic copolymer with or without additional latices, about 1 to 6 parts of a non-ionic surfactant, from 0 to 4 parts of a coalescing agent and from 0 to 5 parts of a co-surfactant, with about 15 to 100 parts of starch, and a propellant in the amount of from about 2% to 10% by weight of the entire composition. The composition is preferably contained under pressure in an aerosol can.
