Copolymers based on (<Emphasis Type="Italic">p</Emphasis>-vinylphenyl)cyclopropylmethyl chlorocinnamate and methyl methacrylate

Abstract—Copolymers of (p-vinylphenyl)cyclopropylmethyl chlorocinnamate with methyl methacrylate were prepared by radical copolymerization. The copolymerization constants were determined, and the Alfrey–Price Q–e parameters were calculated. The possibility of photochemical cross-linking of the copolymer via double bond conjugated with the carbonyl group in the chlorocinnamate moiety and via the cyclopropane ring was demonstrated. The copolymer obtained exhibits sufficiently high photosensitivity (54.5 cm² J^–1) and high refractive index (n _D ²⁰ 1.5890), which opens prospects for using it as a photosensitive base of negative photoresists and in optics.     

Synthesis of Diester Disulfimides from Saccharinmonocarboxylic Acids and Aromatic Diols

The reactions of saccharinmonocarboxylic acids with bisphenol acetates and of saccharinmono-carboxylic acid chlorides with bisphenols yielded the corresponding diester disulfimides.__________Translated from Zhurnal Prikladnoi Khimii, Vol. 78, No. 3, 2005, pp. 444–446.Original Russian Text Copyright © 2005 by Aslanov, Mamedli, Guliev.     

Synthesis and properties of cyclopropane-containing optically transparent polymers

New cyclopropane-containing optically transparent polymers were prepared by radical homopolymerization of p-(2-methoxycarbonylcyclopropyl)styrene and by its binary copolymerization with styrene and methyl methacrylate. The composition and structure of these macromolecular compounds were determined, and their main service characteristics were evaluated.     

Synthesis of diester disulfimides derived from 4- and 5-methoxycarbonyl-2-sulfobenzoic acid imides

Ester interchange of 4-and 5-methoxycarbonyl-2-sulfobenzoic acid imides with glycols was studied.     

Ultraviolet absorption spectra of 2-substituted-1-(<Emphasis Type="Italic">p</Emphasis>-vinylphenyl)cyclopropanes

UV spectra of 2-substituted-1-(p-vinylphenyl)cyclopropanes are studied. Based on spectral data, different substituents (—X) are characterized with respect to their effect on the system of conjugated bonds in the molecule
