What is Trimethylolpropane Trimethacrylate?
Trimethylolpropane trimethacrylate is a vital monomer in acrylate series products. Trimethylolpropane trimethacrylate has high dual bond content, quick treating rate, reduced thickness, high boiling point as well as reduced volatility. It has actually become the most commonly used and also most used multifunctional acrylate responsive crosslinking diluent in the field of radiation curing, and can be made use of for inks, coatings, adhesives, and so on treatable by ultraviolet (UV), radiation or warmth. Castings, and so on.
In the previous art, trimethylolpropane trimethacrylate is gotten by straight esterification of trimethylolpropane (TMP) as well as methacrylic acid (MAA) or trimethylolpropane (TMP) as well as methyl methacrylate (MIXED MARTIAL ARTS) is manufactured by transesterification under the action of a catalyst, as well as the driver utilized is sulfuric acid or p-toluenesulfonic acid. The post-processing procedure of the existing method is cumbersome, the devices is conveniently corroded, and the item cost is reasonably high.
“Fine Petrochemical Industry” 2006, Quantity 23, No. 4, reported a prep work technique of trimethylolpropane trimethacrylate. The method utilizes cerium salt as a catalyst, although it conquers the disadvantages brought by catalysts such as sulfuric acid. Factors, yet the rate of cerium salt stimulant is high, healing is hard, and industrial production is difficult.
Trimethylolpropane Trimethacrylate Uses
- Vulcanizing representative: when artificial rubber is vulcanized with peroxide, usage TMPTMA to improve rust resistance, aging resistance and also rise solidity, heat resistance TMPTMA has a plasticizing impact during mixing, and the original hardening result of vulcanization can be made use of In NBR, EPDM, acrylic rubber.
- Cross-linking representative: TMPTMA can reduce radiation dose, shorten radiation time, rise cross-linking density, as well as has the features of low precision, high cross-linking level, reduced vapor pressure and rapid curing speed. Can be utilized in photocurable inks and also photopolymerizable materials.
- PVC is mixed right into the molding of all PVC solutions for body sealants and also caulking representatives

Application of Trimethylolpropane Trimethacrylate
It can be utilized as a crosslinking aid for peroxide crosslinking and is suitable for blending of cis-1,4- polybutadiene rubber, ethylene propylene diene monomer, ethylene propylene diene monomer, isoprene rubber, butyl and also nitrile rubber
Trimethylolpropane trimethylacrylate (TMPTMA) is used as an intermediate in polymer synthesis in the chemical sector. It is a reactive trifunctional methacrylate, ideal for a variety of polymer crosslinking functions. TMPTMA is specifically suitable for use as an additive in PVC plastisols, plasticizer systems as well as elastomers. Other applications consist of as ingredients for water-based cream, adhesives, as well as UV/EB curing coverings.
Trimethylolpropane trimethylacrylate is a typical trifunctional monomer with higher viscosity than monofunctional and bifunctional monomers, but lower viscosity and better solubility compared with multifunctional monomers. The monomer has fast curing speed, high crosslinking density, and can form a hard, scratch resistant, brittle curing film with excellent solvent resistance. Its price is relatively low. Although it is irritating to the skin, it is still the most commonly used multifunctional monomer. It is an ideal choice for anaerobic adhesives and composite applications of various coatings.
Preparation of Trimethylolpropane Trimethacrylate
Add 40.25g (0.3mol) of trimethylolpropane and 90.41g (1.05mol) of methacrylic acid to the reactor equipped with reflux condenser, water separator, thermometer, stirrer, and air sampling device respectively, and stop polymerization Agent 0.39g (prepared by hydroquinone: phenothiazine=2:1 mass ratio), CZ zirconium-based solid acid catalyst 1.21g, water-carrying agent 100ml (prepared by volume ratio of toluene:cyclohexane=45:55 ), while stirring, the temperature was gradually raised to 85±5°C, and the flow rate of the air continuously kept in the reactor was 7ml/min. is the end point of the reaction), and the filter residue obtained by filtering the reaction solution is a CZ zirconium-based solid acid catalyst (recovered for reuse). Add 2g of activated carbon to the reaction mother liquor, stir and raise the temperature to 45±5°C, maintain it for 15 minutes, filter while hot, and evaporate the solvent from the filtrate after removing the activated carbon under reduced pressure to obtain the target product trimethylolpropane trimethacrylate 110g, purity 98.2%, acid value≤0.5mg/g (acid value detection method is measured by the method of GB 1668-8), esterification rate is 98.2%, (esterification rate detection method is by esterification rate=(1- The acid value of the system after the reaction/the acid value of the system before the reaction)×100 is calculated).
