, p. 5351 - 5355 (2005)
Unique structures of novel ionophores of double-armed penta-crown ethers were successfully synthesized. Diaza 18-crown-6 was designed as the parent crown ring. The penta-crown ethers were prepared by the reaction of trimethylolpropane triacrylate (TMPTA)
Synthesis of novel tris-crown ether structures
Huang, Zhi Bin,Chang, Seung Hyun
, p. 1703 - 1706 (2005)
Six unique tris-crown ether structures were successfully synthesized from trimethylolpropane triacrylate (TMPTA) with amino- and aza-crown ethers through Michael addition. The crown ethers contained a primary amine group such as 2-aminomethyl crown ethers and 4-aminobenzo crown ethers, others contained a secondary amine group, like 1-aza crown ethers.

Paragraph 0021-0042, (2020/07/12)
The invention provides a synthesis method of trimethylolpropane triacrylate. The synthesis method comprises the following steps: step 1, sequentially adding trimethylolpropane, acryloyl chloride, triethylamine, hydroquinone and p-hydroxyanisole into a reaction kettle in proportion; controlling the reaction system to perform stirring reaction at the temperature of 40-60 DEG C for 2-3 hours; and step 2, after the reaction is completed, filtering the reaction solution to remove insoluble solid impurities, washing with water, and drying to obtain the product. Acryloyl chloride is used as a raw material to replace acrylic acid, and the reaction activity of acryloyl chloride is higher than that of acrylic acid so that the reaction temperature is reduced in the synthesis process, and the reactiontime is shortened; acryloyl chloride participates in the reaction, no water is generated, the use of a water-carrying agent methylbenzene or cyclohexane is avoided, the production cost is reduced, and the pollution of the organic solvent to the environment is also avoided.

Paragraph 0010; 0011; 0012; 0013; 0014; 0015, (2017/07/11)
Compared with the prior art, a preparation method of trimethylolpropane triacrylate has the advantages that unreacted substances in reaction products are removed or reduced through resin exchange adsorption, different from neutralization, extraction and washing technologies, no washing wastewater is produced basically in the production process, discharge of wastewater during the production is reduced, exchange resin can be recycled after adsorption saturation and utilized after being activated, and the method is a novel, energy-saving, consumption-reducing and environment-friendly technology. Secondarily, washing is not needed, product waste caused by washing is avoided, the product yield is increased, and the yield can be increased by 5% or above.
Chemoselective Transesterification of Acrylate Derivatives for Functionalized Monomer Synthesis Using a Hard Zinc Alkoxide Generation Strategy

supporting information, p. 3696 - 3699 (2016/08/20)
A new practical method for the synthesis of functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zinc alkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives through the transesterification of commercially available methyl acrylate derivatives with functionalized alcohols under mild conditions.

-
, (2008/06/13)
A polymer electrolyte-forming composition containing (A) a quaternary ammonium salt of general formula (1) below and (B) an ionic liquid can be converted into a polymer without compromising the excellent properties of the ionic liquid, thus enabling an electrolyte having an excellent safety and electrical conductivity and also a broad potential window to be obtained. In formula (1), R1 to R3 are each independently an alkyl group of 1 to 5 carbons or a substituent having a reactive unsaturated bond and any two from among R1 to R3 may together form a ring, and R4 is methyl, ethyl or a substituent having a reactive unsaturated bond, with the proviso that at least one of R1 to R4 is a substituent having a reactive unsaturated bond. X is a monovalent anion, the letter m is an integer from 1 to 8, and the letter n is an integer from 1 to 4.

, (2008/06/13)
The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from >/=1:1 to >/=13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
