Developmental toxicities of methacrylic acid, ethyl methacrylate, n- butyl methacrylate, and allyl methacrylate in rats following inhalation exposure [PDF]

open access: yesToxicological Sciences, 1999
The developmental toxicities of 4 methacrylates were studied in Sprague-Dawley rats after inhalation exposure for 6 h/day, during days 6 to 20 of gestation. The exposure concentrations were, for methacrylic acid, 0, 50, 100, 200, or 300 ppm; for ethyl methacrylate, 0, 600, 1200, 1800, or 2400 ppm; for n-butyl methacrylate, 0, 100, 300, 600, or 1200 ppm;

pH‐Sensitive methacrylic acid–methyl methacrylate copolymer Eudragit L100 and dimethylaminoethyl methacrylate, butyl methacrylate, and methyl methacrylate tri‐copolymer Eudragit E100 [PDF]

open access: yesPolymers for Advanced Technologies, 2019
Poly (methyl methacrylate) derivatives such as Eudragit are largely used for drug encapsulation and in controlled oral drug delivery. With special focusing on those applications, solubilization and precipitation conditions of two pH‐sensitive Eudragit polymers, namely, L100 and E100, were investigated via systematic studies.

Differential orientation and conformation of surface-bound keratinocyte growth factor on (hydroxyethyl)methacrylate, (hydroxyethyl)methacrylate/methyl methacrylate, and (hydroxyethyl)methacrylate/methacrylic acid hydrogel copolymers [PDF]

open access: yesBiointerphases, 2018
The development of hydrogels for protein delivery requires protein–hydrogel interactions that cause minimal disruption of the protein’s biological activity. Biological activity can be influenced by factors such as orientational accessibility for receptor binding and conformational changes, and these factors can be influenced by the hydrogel surface ...

4-Nitrophenyl methacrylate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2008
The title compound, C10H9NO4, was obtained serendipitously during the preparation of benzyl cyclohexylcarbamate. The molecule consists of two approximately planar parts, the nitrophenyl ring and the rest of the non-H atoms, with a dihedral angle of 55.05 (6)° between the two segments. The crystal structure is stabilized by weak C—H...O interactions and

Terpolymerization kinetics of methyl methacrylate or styrene/dodecyl methacrylate/octadecyl methacrylate systems [PDF]

open access: yesPolymer International, 2006
AbstractThis study describes low‐conversion terpolymerization kinetic investigations of methyl methacrylate/dodecyl methacrylate/octadecyl methacrylate (MMA/DDMA/ODMA) and styrene/dodecyl methacrylate/octadecyl methacrylate (ST/DDMA/ODMA) systems. Terpolymerizations were performed isothermally (70–105 °C), in 1 mol dm−3 xylene solutions, using 0.01 mol

Thermal Optical Analysis of Cholesteryl Methacrylate and Methyl Methacrylate Copolymers [PDF]

open access: yesPolymer Journal, 1985
As a side chain type of liquid crystalline polymer, the copolymers of cholesteryl methacrylate and butyl methacrylate were synthesized. When the mesomorphic behavior of the copolymers was examined with a polarized microscope, the observed transition temperatures were so much varied that the mesomorphic behavior had to be studied by thermal optical ...

Copolymerization of Styrene with Dodecyl Methacrylate and Octadecyl Methacrylate

open access: yesCroatica Chemica Acta, 2002
Styrene (Sty) was copolymerized with dodecyl methacrylate (DDMA) and with octadecyl methacrylate (ODMA) in toluene solution using 2,2'-azobis(isobutyronitrile) (AIBN) as a free radical initiator over a wide composition and conversion range. The copolymer composi-tion was determined from NMR spectra.
