3- -propyl methacrylate

Magnesium hydroxide (provided from Skynics), with average particle size of 50 nm, was dried at 110 U under vacuum for 24 h prior to use. 3-(Trimethoxysilyl) propyl methacrylate... 

Hexafluoro-2-(4-fluorophenyl)-2-propyl acrylate (la) and hexafluoro-2-(4-fluorophenyl)-2-propyl methacrylate (lb)7 were prepared by gradually adding a solution of 0.06 mol of acryloyl or methacryloyl chloride, respectively, in 20 ml of tetrahydrofuran (THF), to a cooled solution of 0.04 mol of HFAF in 50 ml of THF containing 0.06 mol oftriethylamine. The mixture was stirred for 10-12 h at room temperature it then was poured into 200ml of water, and the new product was extracted with diethyl ether. After the diethyl ether was evaporated, the crude product was purified by column chromatography using a mixture of hexane and dichloromethane (1 1 by volume) as the elution solvent. Distillation afforded la, b.p. 72-74°C/10"3 mm Hg, and lb, b.p. 48-52oC/103 mm Hg.

Examples of the two macromolecular nomenclature systems are as follows. For source-based names for homopolymers and copolymers polyacrylonitrile, poly(mcthyl methacrylate), polylacrylamidc-co-vinylpynolidinone), polybutadiene-felocJ-polystyrene, and poly(propyl methacrylate)-gra/t-poly( 1-vinylnaphthalene). Structure-based examples arc as follows polyloxy-l,4-phcnylcnct (1), po]y(oxycthyl-cncoxytcrcph-thaloy) (2) and poly[imino(l-oxo-l,6-hexanediyl)J (3).
