The method described below for butyl a-cyanoacrylate is generally applicable to mononiers ranging from methyl to decyl based on modification of the work of Jeremias.6 The procedure adopted was as follows. First Aid Measures and Personal Protection: Poly(methyl 2-cyanoacrylate) precipitates when the solution is poured into a compressed-air-driven blender containing 200 ml of anhydrous ethyl ether (Note 6). Methyl cyanoacrylate (MCA) is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. 0000060907 00000 n Poly(methyl methacrylate) (PMMA) standards were used for molecular weight calibration. 0000001190 00000 n 0000090893 00000 n Their general chemical formula is CH 2 =C(CN)CO 2 R, with R representing an organic—e.g., methyl (CH 3 )—molecular group. /Linearized 1 Polymerized set form of methyl cyanoacrylate instant glue. << /Length 397 >> Royston, SG8 7SL, UK, Tel: +44 (0) 1763 208 503 e Assumes 100% efficiency of initiation. 0000002040 00000 n Additional Names: 2-cyanoacrylic acid methyl ester; MCA; mecrilate; mecrylate; methyl 2-cyanoacrylate; methyl a-cyanoacrylate.
