专利号:US-11034664-B1 优先权日:2020-05-11 标题 :Synthesis of cyclic carbonate monomers 发明人:PARK NATHANIEL H; HEDRICK JAMES L; PIUNOVA VICTORIA A; ARRECHEA PEDRO; ERDMANN TIM 权利人:IBM 摘要:Techniques regarding the synthesis of cyclic carbonate monomers are provided. For example, one or more embodiments described herein can comprise a method, which can include cyclizing a functionalized diol monomer with N,N′-carbonyldiimidazole, wherein the cyclizing produces a cyclic carbonate monomer and an imidazole carbamate. The method can also include activating the imidazole carbamate with an acid, wherein the activating promotes cyclization of the imidazole carbamate into the cyclic carbonate monomer.
专利号:WO-2024260915-A1 优先权日:2023-06-19 标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof 发明人:GARMSHAUSEN YVES 权利人:XOLO GMBH 摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.
专利号:US-11292873-B2 优先权日:2013-11-05 标 题 :Etheramines prepared from a mixture of two or more multifunctional alcohol initiators, and their use as curatives or intermediates for polymer synthesis 发明人:ZHOU HUI; LEWIS DAVID C; KLEIN HOWARD P; RENKEN TERRY L; PATTERSON LEAH 权利人:HUNTSMAN PETROCHEMICAL LLC 摘要:Implementations described herein generally relate to etheramine mixtures formed from a mixture of two or more multifunctional alcohol initiators, processes for the etheramine mixtures production, and its use as a curing agent or as a raw material in the synthesis of polymers. In one implementation, the process comprises mixing a polyol initiator having a melting point greater than a processing temperature and a polyol initiator having a melting point less than the processing temperature to form a polyol initiator mixture having a melting point less than the processing temperature, charging the polyol initiator mixture to an alkoxylation reaction zone, contacting the polyol initiator mixture with an alkylene oxide in the alkoxylation reaction zone to provide a mixture of alkoxylated precursor polyols and charging the mixture of alkoxylated precursor polyols to a reductive amination zone and reductively aminating the mixture of alkoxylated precursor polyols to form the etheramine mixture.
专利号:WO-8503665-A1 优先权日:1984-02-15 标题:Synthesis of polyurethane products 发明人:HOSTETTLER FRITZ 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.
