Catalysis for the synthesis of methacrylic acid and methyl methacrylate

Chemical Society Reviews, 2018
Methyl methacrylate (MMA) is a specialty monomer for poly methyl methacrylate (PMMA) and the increasing demand for this monomer has motivated industry to develop clean technologies based on renewable resources.

Effect of methacrylic acid:Methyl methacrylate monomer ratios on polymerization rates and properties of polymethyl methacrylates

Journal of Biomedical Materials Research, 1997
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 ...

The copolymerization of phenyl methacrylate with methacrylic acid

Polymer Science U.S.S.R., 1970
Copolymers of methacrylic acid with its esters are used as models in the hydrolysis s tudy of the respective polymethacrylates [1]. The knowledge of copolymerization constants rl and r2 permits the calculation of the acid and ester unit distribution in the copolymer chains. In this event the kinetic s tudy of the hydrolysis of copolymer samples enables

Enzymatic synthesis of sorbitan methacrylate: Comparison of methacrylic acid and vinyl methacrylate

Biochemical Engineering Journal, 2006
Abstract “Biomaterials” is a generic term which refers to a variety of medical material which is designed to be in direct contact with living tissue. Clearly, biomaterials must be carefully and microscopically fabricated for optimal acceptance within the living organism, in both functional and structural senses. In this study, the enzymatic synthesis

Organotin polymers—I. Copolymerization parameters of tributyltin methacrylate with methyl methacrylate, propyl methacrylate and butyl methacrylate

European Polymer Journal, 1979
Abstract The monomer reactivity ratios for radical copolymerizations of tributyltin methacrylate (monomer-1) with methyl methacrylate, propyl methacrylate and butyl methacrylate have been found as r 1 = 0.79 and r 2 = 1.0, r 1 = 0.58 and r 2 = 0.9, and r 1 = 0.65 and r 2 = 0.68 respectively.

Studies on blood compatibility of terpolymers composed of methyl methacrylate, methoxypolyethyleneglycol methacrylate, and dimethylsiloxane methacrylate

Journal of Biomaterials Science, Polymer Edition, 1998
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,

Isocyanato Urethane Methacrylates Derived from Hydroxyethyl Methacrylate

Journal of Dental Research, 1980
Isocyanato 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.

Copolymerization of methacrylic acid with methyl methacrylate by SET‐LRP

Journal of Polymer Science Part A: Polymer Chemistry, 2010
AbstractSingle‐electron transfer living radical polymerization (SET‐LRP) has developed as a reliable, robust and straight forward method for the construction well‐defined polymers. To span an even larger variety of functional monomers, we investigated the copolymerization of methyl methacrylate with methacrylic acid by SET‐LRP.
