Softwood Lignin-Based Methacrylate Polymers with Tunable Thermal and Viscoelastic Properties
, 2016Softwood (guaiacylic) lignin-based methacrylate polymers (LBMPs) that exhibit excellent glass transition temperatures (Tg’s), desirable thermal stabilities (greater than 100 °C above Tg), and intermediate shear-flow resistances, in comparison to ...

Refractive index measurements of poly(methyl methacrylate) (PMMA) from 0.4-1.6 μm.
Applied Optics, 2015Using a transmission-spectrum-based method, the refractive index of a 50 μm thick sample of poly(methyl methacrylate) (PMMA) was measured as a function of wavelength.

Five binary formulations were prepared from methyl methacrylate (MMA) and methacrylic acid (MAA) monomers, and six ternary formulations were prepared from polysols of 30% wt polymethyl methacrylate (PMMA)/MMA and MAA. Using thermal analyses (DSC and TGA) the polymerization kinetics, condition of postcuring, relative amount of residual monomers, and ...

Terpolymers composed of methyl methacrylate (MMA), polydimethylsiloxane methacrylate (PDMSMA), and methoxypolyethyleneglycol methacrylate (MPEGMA), having different compositions were synthesized. Platelets were not adsorbed onto terpolymer surfaces composed of 50 wt% MMA, 25 wt% PDMSMA and 25 wt% MPEGMA, while on terpolymers with the other compositions,

Poly(n-propyl methacrylate) is known to be immiscible with poly(methyl methacrylate) (PMMA). However, we have found that poly(methoxymethyl methacrylate) is miscible with PMMA, indicating the importance of ether oxygen atoms in achieving miscibility. On the other hand, poly(methylthiomethyl methacrylate) is immiscible with PMMA.

Isocyanato Urethane Methacrylates Derived from Hydroxyethyl Methacrylate
Journal of Dental Research, 1980Isocyanato urethane methacrylates were synthesized from five diisocyanates and hydroxyethyl methacrylate. They may be homopolymerized or copolymerized with other methacrylates by the usual free radical methods of initiation and have potential as adhesion-promoting agents for dentin.

Microstructure of copolymers of methyl methacrylate with ethyl methacrylate
European Polymer Journal, 1988Abstract The reactivity ratios for the copolymerization of methyl and ethyl methacrylates were calculated by the method of Kelen and Tudos. The triad sequence distributions were then determined by means of a computer program due to Harwood. The calculated distributions agree well with those found by 13 C- 1 H-NMR spectroscopy.
