Telechelic Oligo(N-Vinylpyrolydone)swith Cumene Based Terminal Groups for Block-Copolymer and Nanoparticle Obtaining

Polymers with terminal epoxy, phosphate, fluoroalkyl groups were obtained by radical polymerization in the presence of chain transfer agents derived from isopropylbenzene. The structure of polymers was confirmed by NMR spectra and functional analysis. Polymers with functional fragment were used for synthesis of polymer-inorganic particles and copolymers with poly(2-ethyl-2-oxazoline) fragment.

Direct Synthesis and Characterization of Photo-Crosslinkable Biodegradable PLA-PEG-PLA Ttiblock Copolymer with Methacrylates Functions by Green Montmorillonite Clay Catalyst

Di-methacrylated PLA-PEG-PLA triblock copolymers of polylactide and polyethylene glycol were synthesized in one-step process by bulk cationic polymerization of lactide in the presence of PEG with different average molecular weights, using Maghnite-H+, an acidic montmorillonite clay, as a solid non-toxic catalyst. The obtained di-methacrylated copolymer was analyzed by 1H NMR and DSC.

Design of polymers of block, comb-like and highly branched structures with peroxide-containing chains

The tailored synthesis of telechelic oligoperoxides (TO), oligoperoxide metal complexes (OMC) as well as the development of controlled radical polymerization in aqueous and hydrocarbon media initiated by them provides prospective approaches for the obtaining block, comb-like and highly branched polymers with the backbone and branches of various nature, polarity, length and reactivity. The polymer-precursors and final products were investigated by chemical, spectral and rheological techniques.
