Relative Reactivities in Vinyl Copolymerization
Synopsis. From data in the literature on relatine rates of copolymerization it has been possible to evaluute two constants, Q and e , cheracteristic of a n individual monomer, which appear to account satisfactorily .for its behavior in copolymerization. The constant Q describes the “general monomer reactivity” and is apparently related to possibilities for stabilization in a radical adduct. The...
متن کاملN-(2,3-Dimethylphenyl)succinimide
In the title compound, C(12)H(13)NO(2), the dihedral angle between the aromatic benzene ring and the imide segment is 67.7 (1)°. The mol-ecules in the crystal are packed into layered chains along the c axis.
متن کاملMiniemulsion Copolymerization of Ethylene and Vinyl Acetate
The copolymerizations of a gaseous monomer (ethylene) and a liquid monomer (vinyl acetate) via emulsion and miniemulsion polymerizations are reported. Reactions in which the vinyl acetate was introduced in both batch and semibatch modes are carried out. (Ethylene introduction is always in a semibatch model since the polymerization is carried out under a constant pressure of ethylene in the reac...
متن کاملCopolymerization of Vinyl Chloride by Organometallic Compounds
ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...
متن کاملN-(2,6-Dimethylphenyl)succinimide
The mol-ecule of the title compound, C(12)H(13)NO(2), lies on a twofold rotation axis that passes through the N and C(para) atoms as well as through the mid-point of the bond between the methyl-ene C atoms. The dihedral angle between the aromatic ring and the amide segment is 75.9 (1)°.
