4-chloromethyl styrene homopolymer and its copolymers with styrene were prepared from their corresponding 4-chloromethyl styrene and styrene monomers at 1:0, 1:1, 1:3 and 1:5 mole ratios. these homo- and copolymerswere synthesized by radical polymerization in presence of aibn as initiator and dry toluene as solvent. then, chloromethyl groups were converted into azidomethyl groups on the homo- a...

4-chloromethyl styrene (cms) was copolymerized with different monomers such as methyl methacrylate (mma), methyl acrylate (ma), 2-ethylhexyl acrylate (eha) by free radical polymerization method at 70 ±1°c using a,a'-azobis(isobutyronitrile) (aibn) as an initiator. the copolymer compositions were obtained using related 1hnmr spectra and the polydispersity of the copolymers were determined using ...

4-ChloroMethyl Styrene (CMS) was copolymerized with different monomers such as Methyl MethAcrylate (MMA), Methyl Acrylate (MA), 2-EthylHexyl Acrylate (EHA) by free radical polymerization method at 70 ±1°C using a,a'-Azobis(IsoButyroNitrile) (AIBN) as an initiator. The copolymer compositions were obtained using related 1HNMR spectra and the poly...

In this work, we investigated a simple one-step process for the formation of chemical bonds between multi-walled carbon nanotubes (MWCNTs) and benzyl-type side chain radicals generated by UV photolysis of polystyrene derivatives containing the chloromethyl (–CH2Cl) group. Poly(4-chloromethyl)styrene, or styrene/4-(chloromethyl)styrene random copolymer, was mixed with MWCNTs in 1-methyl-2-pyrrol...

Exfoliated poly (Chloromethyl styrene-co-styrene)-g-polyacrylonitryle/organo- modified montmorillonite [P(CMSt-co-St)-g-PAN/O-MMT] nanocomposite was synthesized through solution intercalation method by using atom transfer and nitroxide mediated radical polymerization. At first, poly (chloromethyl styrene-costyrene) copolymer was synthesized by nitroxide - mediated “living” free radical polyme...

Free radical copolymerization and cross-linking copolymerization of the 4-chloromethyl styrene (CMS) with styrene (in various mole ratios), were carried out using α,α-azobis(isobutyronitrile) AIBN as initiator and 1,4divinylbenzene (DVB) as a crosslinking agent at 70 oC. The antimicrobial 4-hydroxybenzoic acid (4-HBA) was covalently attached to the obtained copolymers with replacement of all th...

Chemical modification of chloromethylstyrene - styrene copolymer throughout reaction p-substituted carboxylic acid group bis-(4,4`-dibromo)-4``-triphenylamine with the chloromethyl attached to a phenyl was carried out on soluble and polymeric cross-linked copolymer. oxidation neutral triphenylamine antimony pentachloride in dichloromethane solvent gives corresponding cation radical salt counter...
