“…Many copolymers with reactive functional groups are now being synthesized, tested and used not only for their macromolecular properties, but also for the properties of functional groups [1]. These functional groups provide an approach to a subsequent modification of the polymer for the specific end applications [2]. Nowadays, a strong demand prevails for -functional polymer‖ with very specific properties.…”

“…Among these, radical scavenging functional polymers have emerged as powerful tools that are suitable for polymeric stabilizers, self-stabilized materials, biomedical materials and packing materials [2][3][4][5][6]. Our interest in the development of radical scavenging polymer based on sterically hindered phenol (SHP) function-alized norbornene derivatives and ring-opening metathesis polymerization (ROMP) strategies had led us to recently communicate a series of polymers bearing SHP group in the side-chain and their performance in the scavenging of radicals.…”

Novel norbornene derivatives bearing a 3,5-di-tert-butyl-4-hydroxyphenoxy (DBHO) group were synthesized and used as sterically hindered phenol functionalized norbornene monomers (1-4). The ring-opening metathesis polymerization (ROMP) of these functional monomers was carried out with a typical ruthenium catalyst (bis(tricyclohexylphosphine)benzylidene ruthenium (IV) dichloride, a Grubbs first-generation catalyst) to prepare sterically-hindered phenol-functionalized polymers possessing radical scavenging function. The resulting polymers bearing a DBHO side-chain were characterized by means of gel-permeation chromatography, 1 H-NMR and 13 C-NMR. The radical scavenging ability of polymers was determined using the α,α-diphenyl-β-picrylhydrazyl (DPPH·) free radical. Due to the electron-donating effect of the oxygen atom located in the para-position of phenol, the resulting polymers showed high efficiency to scavenge DPPH· free radical. The molecular weight of polymers was dependent on the molar ratio of monomer to catalyst ([M]/[C]), and the ROMP activity was dependent on the stereostructure of monomers themselves.

These groups provide an approach to a subsequent modification of the polymer for specific end application [4]. Czeh and coworkers synthesized acrylic pressure sensitve adhesives with the help of azo-prester radical initiators [5].…”

Abstract. The acrylate monomer, 7-acryloyloxy-4-methyl coumarin (AMC) has been synthesized by reacting 7-hydroxy-4-methyl coumarin, with acryloyl chloride in the presence of NaOH at 0-5°C. Copolymers of 7-acryloyloxy-4-methyl coumarin (AMC) with vinyl acetate (VAc) were synthesized in DMF (dimethyl formamide) solution at 70±1°C using 2,2′-azobisisobutyronitrile (AIBN) as an initiator with different monomer-to-monomer ratios in the feed. The copolymers were characterized by Fourier transform infra red (FTIR) spectroscopy. The copolymer composition was evaluated by 1 H-NMR (proton nuclear magnetic resonance) and was further used to determine reactivity ratios. The monomer reactivity ratios for AMC (M1)-VAc (M2) pair were determined by the application of conventional linearization methods such as Fineman-Ross (r1 = 0.6924; r2 = 0.6431), Kelen-Tüdõs (r1 = 0.6776; r2 = 0.6374) and extended Kelen-Tüdõs (r1 = 0.6657; r2 = 0.6256). Thermo gravimetric analysis showed that thermal decomposition of the copolymers occurred in single stage in the temperature range of 263-458°C. The molecular weights of the polymers were determined using gel permeation chromatography.The homo and copolymers were tested for their antimicrobial properties against selected microorganisms.
