Elastic and swelling behavior of 2-hydroxyethyl methacrylate, diethylene glycol methacrylate, and methacrylic acid copolymers

Journal of Applied Polymer Science, 1997
The elastic and swelling behavior of copolymers of 2-hydroxyethyl methacrylate, diethylene glycol methacrylate, and methacrylic acid crosslinked with ethylene glycol dimethacrylate has been studied. In the range of copolymer composition studied, Young's modulus of the swollen networks increases with the content of methacrylic acid, and its dependence ...

Preparation of methacrylate monoliths

Journal of Separation Science, 2007
AbstractRigid macroporous polymers developed in the early 1990s are widely used as efficient stationary phases for all types of chromatographic separations. The main advantages of so‐called monolithic supports are their high hydraulic permeability and the dominance of the convection over the diffusion mechanism of mass‐exchange under dynamic conditions

Microstructure of copolymers of methyl methacrylate with ethyl methacrylate

European Polymer Journal, 1988
Abstract 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.

Development of reactive methacrylates based on glycidyl methacrylate

Journal of Polymer Science Part A: Polymer Chemistry, 2010
AbstractSix methacrylate monomers have been synthesized for use as reactive diluents in dental composites and evaluated to investigate the relationship between molecular structure and monomer reactivity. Four were synthesized by reactions of glycidyl methacrylate (GMA) with various acids, 2‐(2‐methoxyethoxy)acetic acid (1), 2‐(2‐(2‐methoxyethoxy)ethoxy)

Stereoregular Copolymers of Methacrylic Acid and of Methyl Methacrylate

Journal of Macromolecular Science: Part A - Chemistry, 1971
Abstract Different techniques and mechanisms of hydrolysis of isotactic, syndiotactic, and atactic PMMA are compared for over-all rates and reaction yields. A combined hydrolysis using a mixture of hydriodic and acetic acid gave the best results, and included the conservation of tacticity and size of the acid-ester copolymers obtained.

A study of the copolymerization of hydroxyethyl methacrylate and tetrahydrofurfuryl methacrylate

Journal of Polymer Science Part A: Polymer Chemistry, 1999
The free radical copolymerizations of hydroxyethyl methacrylate and tetrahydrofurfuryl methacrylate have been investigated at 50 degrees C. The compositions of polymers prepared at low conversions have been determined using C-13-NMR, and the glass transition temperatures determined by DSC.

Copolymerizations of 2-hydroxyethyl methacrylate with alkyl methacrylates

European Polymer Journal, 1979
Abstract Copolymerizations of 2-hydroxyethyl methacrylate with ethyl methacrylate and n -butyl methacrylate were studied in bulk at temperatures between 60 and 80° using benzoyl peroxide as initiator. The monomer reactivity ratios were calculated using Joshi-Joshi, Fineman-Ross and intersection methods.

Copolymerization and copolymers of styrene with dodecyl methacrylate and octadecyl methacrylate

1999
Styrene (St) was copolymerized with dodecyl methacrylate (DDMA) or octadecyl methacrylate (ODMA) in toluene using AIBN as free radical iinitiator over a wide composition and conversion ranges. The copolymer composition was determined from H-NMP spectra. The copolymerization reactivity ratios were determined. The Q and E values were also calculated. The
