4-Nitrophenyl methacrylate [PDF]
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&

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