Abstract:
A novel interpenetrating polymer network was prepared by using new cycloaliphatic epoxy resin (CER), methylhexahydrophthalic anhydride (MeHHPA) and trimethylolpropane trimethacrylate (TMPTMA) as matrix resins. Since the radical polymerization reaction of TMPTMA precedes the cationic polymerization reaction of CER and MeHHPA, a step-by-step interpenetrating polymer network is obtained. Finally, the step-by-step interpenetrating polymer network does not appear obvious microscopic phase separation phenomenon. The effect of TMPTMA content on the electrical properties of hundred-cross network polymer was investigated. The results show that the AC resistance of CER/TMPTMA interpenetrating polymer networks at different temperatures is related to the composition and microstructure of the system. With the increase of TMPTMA content, the breakdown strength and morphology parameters of CER/TMPTMA interpenetrating polymer network increase, and the polymer uniformity of interpenetrating polymer network increases gradually.Key words:

Abstract:
with 4-vinyl pyridine (4-VP) as functional monomer, divinyl benzene (DVB) and trimethylolpropane trimethacrylate (TRIM) as mixed crosslinking agent, azobisisobutyronitrile (AIBN) as initiator, acetonitrile as reaction medium, monodisperse polymer microspheres were prepared by precipitation polymerization. The effects of polymerization conditions such as comonomer, solvent and initiator on the particle size, dispersion and yield of polymer microspheres were investigated. The microspheres were characterized by scanning electron microscopy (SEM), laser particle size analyzer, thermogravimetric analyzer and infrared spectroscopy. The results show that the surface morphology and yield of polymer microspheres can be controlled by changing the volume of solvent, the molar ratio of monomer/crosslinking agent and the concentration of initiator. Decreasing the volume of acetonitrile solution, increasing the molar ratio of DVB and the molar ratio of crosslinking agent can increase the particle size and particle size distribution uniformity of polymer, it increases with the increase of the molar ratio of crosslinking agent and the concentration of initiator. Under the optimal conditions, the molar ratio of DVB and TRIM is 4:1, the molar ratio of monomer/crosslinking agent is 1:5, when the amount of acetonitrile was 5.6 m L (monomer and crosslinking agent accounted for 7% of the volume of the medium), the concentration of initiator was 2 wt%~ 6 wt%(the amount of total reaction monomer), monodisperse poly(4-VP-co-DVB/TRIM) microspheres with regular morphology and high yield were obtained. The average particle size of the microspheres was about 4.02 μm, and the particle size distribution Index (U) was 1.013. In addition, the thermogravimetric analysis showed that the polymer microspheres began to decompose at 350 ℃, and the weight loss reached 600 at 84.9% ℃.

Abstract:
The invention discloses a method for synthesizing trimethylolpropane trimethacrylate. Trimethylolpropane and methacrylic acid are loaded with Heteropoly acid, polymerization inhibitor methylhydroquinone THQ, and water-carrying agent alkane in catalyst MCM-41, the trimethylolpropane trimethacrylate is obtained by reacting the fatty acid ester or alkane in the presence of one or more of the fatty acid esters for 4 to 6 hours. In the present invention, methylhydroquinone THQ is used as a polymerization inhibitor for the reaction, and a good polymerization inhibiting effect is obtained at a high temperature. The reaction uses MCM-41 of the heteropoly acid load as the catalyst of the reaction, increases the specific surface area of the catalyst, the esterification rate of the reaction can reach more than 90%, and the catalyst of the reaction can be recycled, the reaction uses alkane, one or more fatty acid esters or alkanes and fatty acid esters are mixed as water-carrying agents to realize the green preparation process in production.

introduction | trimethylolpropane triacrylate (Trimethylolpropane Triacrylate, abbreviation: TMPTA) is a typical trifunctional monomer, its viscosity is higher than that of monofunctional and bifunctional monomers, but compared with polyfunctional monomers, its viscosity is relatively low and it has good solubility. The monomer can provide high curing speed and high crosslinking density, and can form a cured film with excellent solvent resistance, hard scratch resistance and brittle. Its price is relatively low. Although it is irritating to the skin, it is still the most commonly used multifunctional monomer. |

Crosslinking agent: TMPTMA can reduce radiation dose, shorten radiation time, improve cross-linking density, and has the characteristics of low precision, high cross-linking, low steam pressure and fast curing speed. Can be used for photocurable inks and photopolymeric materials. 3.
