    摘要： There is described a formaldehyde-free laminating adhesive, optionally the with less than 3% by weight of co-solvent(s), the adhesive comprising: (I) a polyurethane that comprises from 30% to 65% by weight of hard segments, the polyurethane being obtained and/or obtainable from a first polyurethane dispersion (PUD) comprising the reaction product of (A) an organic isocyanate and (B) at least one chain extender reacting in a respective stoichiometric ratio (NCO to NCO reactive group) from 1:1 to 1:2.5 and; optionally the NCO reactive group(s) of the chain extender comprises one or more hydrazinyl-like group(s) (denoting isocyanate reactive groups selected from the group comprising, preferably consisting of: —NRNR2 (hydrazinyl groups); —CONRNR2 (hydrazidyl groups), —NRCONRNR2 (semicarbazidyl groups); and —ONR2 (oxyamine groups), where each R is independently selected from H or C1-10hydrocarbo); and (II) optionally a second polymer obtained and/or obtainable from a polymer precursor comprising at least one unsaturated moiety, preferably an ethylenically unsaturated group, and where optionally the second polymer may be iminated; with the provisos that: (α) when the first polyurethane does not comprise hydrazinyl-like group(s) then the second polymer is iminated; and (β) when the second polymer is un-iminated or is absent then the first polyurethane comprises hydrazinyl-like group(s). These adhesives may be used to adhere surface veneers to wood and/or to laminate the layers within plywood.

    摘要： A novel method of preparing an aqueous dispersion of non-uniform polyurethane particles which comprises (a) preparing at least two isocyanate-terminated polyurethane prepolymers having different hydrophilicities; (b) preparing a uniform mixture of said prepolymers; and (c) dispersing the mixed prepolymers in an aqueous medium. The resulting dispersion of the prepolymers may optionally be chain extended. This method enables the preparation of core-shell particles as well as particles of other morphologies, including “raspberry”, interpenetrating network, “salt-and-pepper”, “ice-cream cone” and particles of gradient composition. Similarly, an aqueous dispersion of two different polyurethane polymers may be obtained by first preparing at least two different isocyanate-terminated polyurethane prepolymers, preparing a uniform mixture of such prepolymers and thereafter dispersing the mixture in an aqueous medium.

    摘要： An aqueous dispersion of nanoparticle/polyurethane composites is made by forming a mixture of nanoparticles and a continuous mass of a polyurethane prepolymer in the substantial absence of water and dispersing the mixture so made in aqueous medium. Alternatively, a polyurethane prepolymer or a mixture of nanoparticles and a continuous mass of a polyurethane prepolymer is dispersed into an aqueous dispersion of nanoparticles.
