4-Nitrophenyl methacrylate [PDF]

Acta 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

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

Polymers 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.

The thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) [PDF]

Journal of the Serbian Chemical Society, 2000
The non-oxidative thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) was investigated by studying changes in the polymer residue. Due to the different number of β-hydrogens in their ester substituents, these two

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

Toxicological 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;

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]

Biointerphases, 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 ...
