“…This is has been obviously connected with influence of the chlorine atoms located at the cyclopropane ring on the vinyl group through a three-membered cycle and an increase of a degree of conjugation in the monomer molecule. This fact is confirmed by the data of UV spectrum of the monomer of DCCPS [9]. It has been seen from found copolymerization constant values that for systems (I-III) + MAA both types of formed radicals react more faster with "foreign" monomer than with their "own", and in the formation of macromolecules of copolymers are inclined to links alternation (r 1 ·r 2 <<1).…”

The radical copolymerization of p-cyclopropyl styrene (1) and its monochloro-(II) and gemdichloro-substituted derivatives with methacrylic acid was carried out. The composition and structure of these copolymers was established. It revealed that the copolymerization reactions proceed with opening of double bond of the vinyl group (I-III) of monomers and methacrylic acid. Also, copolymerization constants were determined and Q−e parameters on Alfrey-Price and copolymer microstructure calculated. It found that the synthesized copolymers were characterized by effective light transmission (88-90 %) and optical index.

“…The constant values of relative activity (Table 1) indicate to greater reactivity of CPhCCS in comparison with styrene and MMA, which has been connected with influence of substituent at p-chlorophenoxycarbonyl)cyclopropyl styrene of cyclopropane ring on electron density of double bond of the vinyl group [16]. The ester group is included in the general conjugation system, causing electron density redistribution both in the monomer and in the radical center formed from it.…”

The radical copolymerization of (p-chlorophenoxycarbonyl)cyclopropyl styrene with styrene and methyl methacrylate has been carried out. New cyclopropane-containing copolymers have been obtained. It has been established that the synthesized copolymers due to peculiarities of their structure and polyfucntionality, namely with content of carbonyl and cyclopropane groups sensitive to UV irradiation in the macromolecule have photosensitivity. The constant values of relative activity of monomers have been determined and Q-e parameters on Alfrey and Price have been calculated. The copolymerization constants of this compound (r1) with styrene and methyl methacylate (r2), calculated on Fineman-Ross method are: r1 = 1.1 and1.05, but r2 = 0.56 and 0.48, respectively; Q and e parameters values: Q1 = 3.1 and 2.4, e1 = –1.4 and –0.8, respectively. The photochemical structuring has been investigated and it has been shown that the structuring process proceeds due to of cyclopropane ring opening and carbonyl group. The composition and structure of these copolymers have been established and their some characteristics (heat resistance, hardness, adhesive strength, water absorption) have been investigated. The structuring process has been also studied and it has been established that the synthesized copolymer has relatively high photosensitivity (50–55 cm2J-1)

Radical copolymerization of (p-vinylphenyl)cyclopropylmethyl cinnamate with styrene was studied. A new cyclopropane-containing photosensitive copolymer was prepared. The composition and structure of the synthesized copolymer and the relative activity constants of the monomers were determined, and the Q-e parameters were calculated. The dependence of the photosensitivity on the copolymer composition was revealed.
