标题:Synthesis of aqueous, anionic, amino acrylate polymers
发明人：DAS SURYYA K; KILIC SONER

摘要:Disclosed is a method of making aqueous, anionic amino polymers in water from olefinically unsaturated monomers including amine-containing monomers, but substantially without the inclusion of acid-group containing monomers. The polymerization of the amino polymer is carried out in the presence of a carboxy functional azo initiator dissolved in water by neutralization of acid groups present on the initiator. The polymer is useful in single-package or two-package coating compositions having pH above 7.0 that may be cured with polyisocyanates or polyepoxides.

标题 :Synthesis of photoreactive polymeric binders

摘要:A photoreactive binder that may be used to enhance photospeed in either conventional plates or on-press developable lithographic printing plates. Briefly, a polymer of m-isopropenyl- alpha , alpha -dimethylbenzyl isocyanate is derivatized for vinyl group reactivity by reacting the isocyanate groups thereof with hydroxyalkyl acrylate. The resulting photopolymeric binder provides significantly higher photospeed than the non-reactive binder currently utilized in the production of conventional printing plates. The resulting lithographic printing plate also shows better durability (as manifested by longer run-length) and is more easily developed by the microencapsulated developers utilized in the present invention. As to the preparation of the photoreactive binders, the application discloses a method of copolymerizing m-isopropenyl- alpha , alpha -dimethylbenzyl isocyanate (m-TMI) through complexation with an electron-deficient monomer such as maleic anhydride to accelerate free radical copolymerization with other monomers, and thus, provides greater monomer-to-polymer conversion. Use of the resulting product in the photoresist of a lithographic printing plate improves its adhesion to an underlying substrate.

标 题:Fluorinated thermoset polyurethane elastomers prepared from polyether prepolymers formed from mono-substituted fluorinated oxetane monomers

摘要:This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative of 3-hydroxymethyl-3-methyloxetane premonomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains. Additionally, the fluorinated oxetane monomers can be copolymerized with non-fluorinated monomers such as tetrahydrofuran to give polyether prepolymers with improved hydrocarbon compatibility. These prepolymers are polydisperse and exhibit number average molecular weights from 5,000 to about 50,000. These prepolymers are amorphous oils with primary hydroxy end-groups and thus function efficiently as the soft block for the synthesis of a variety of thermoset/thermoplastic elastomers and plastics having the characteristics of very low surface energy, high hydrophobicity, low glasss transition temperature and low coefficient of friction. The polyurethanes derived from the prepolymers of this invention are elastomeric and, in addition to the above characteristics, exhibit high moisture resistance, high tear strength and excellent adhesion to a variety of substrates.

摘要:The present invention is directed to polyhydroxyl compounds containing both ether and ester groups, having an average hydroxyl functionality of 2 to 6 and an average hydroxyl number of about 100 to 600, based on the esterification product of (i) polyether polyols having an average hydroxyl functionality of 3 to 8 and an average hydroxyl number of about 200 to 1000 with (ii) about 5 to 70 equivalent %, based on the hydroxyl group of component (i) and the carboxyl group of component (ii), of organic monocarboxylic acids. The present invention is also directed to the use of the polyhydroxyl compounds as synthesis components in the production of polyurethane plastics materials by the isocyanate-polyaddition process, particularly their use as the polyol component in two-component polyurethane coating agents and/or polyurethane casting systems which are solvent-free or have a low solvent content.
