摘要:The present invention provides an aqueous polyurethane (PU)-polyacrylate hybrid dispersion obtainable by free radical polymerization of at least one acrylate polymer (A1) in the presence of at least one polyurethane (P1), a process for preparing these aqueous polyurethane-polyacrylate hybrid dispersions, wherein said process comprises a) preparing an aqueous polyurethane dispersion and b) using the polyurethane dispersion thus prepared as raw material for the further synthesis of a polyacrylate dispersion, and the use of the hybrid dispersion thus obtained as binder in filled coating materials, particularly as a binder for flexible roof coatings.

标题 :Process for synthesis of telechelic urethane acrylate UV curable pre-polymeric materials

摘要:The present invention involves the design of a radiation curable organic pre polymer resin material based on urethane acrylic linkage synthesized from the natural renewable resource cardanol or a derivative thereof, for coating application. These new molecules have a faster and better curing rate compared to the starting renewable resource—cardanol. This is brought about by the hydrogen bonding of the urethane linkage which leads to a pre organization of the molecules in such a way as to bring the cross linkable double bonds closer to each other. The present invention also involves a UV curable formulation of the above mentioned resins along with 2-10 parts by weight of a photopolymerization initiator. The resin, either in a formulation or alone turns into a cross linked film upon photopolymerization in presence of photoinitiator under a UV curable radiation source like a mercury vapor pressure lamp.

标题:Synthesis of polyurethane products

权利人:PIRRI JAQUELYN P; HOSTETTLER FRITZ
摘要:Wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin microcellular products, obtained by the reaction of (a) a polyisocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, and at least one urethane, $(1,5)omicronp. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient of friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, in particular, two and three component systems are useful in molding operations, e.g., manufacture of shoe soles.

摘要:The instant invention is directed to a process for the production of diisocyanate mixtures of 2,4-diisocyanato toluene and 2,6-diisocyanato toluene, having from 36 to 90% by weight, based on the total mixture, of 2,6-diisocyanato toluene, comprising: trimerizing some of the isocyanate groups of a diisocyanate mixture of 2,4-diisocyanato toluene and 2,6-diisocyanato toluene, having a maximum content of 2,6-diisocyanato toluene of 35% by weight based on the total mixture and isolating from the reaction mixture which is thus obtained, a diisocyanate mixture having an increased content of 2,6-diisocyanato toluene. The invention is also directed to the use of these mixtures as synthesis components in the production of polyurethane elastomers.
