Radiation graft post-polymerization of sodium styrene sulfonate onto polyethylene

Post-irradiation grafting of sodium styrene sulfonate (SSS) in the presence of acrylic acid (AA) has been investigated on polyethylene (PE) pre-exposed to gamma radiation at room temperature in the air. Special attention was paid to the effect of low molecular weight salt additives on the kinetics of graft copolymerization of SSS and AA. The presence of SSS links in the grafted PE copolymers wa...

Controlled nitroxide-mediated styrene surface graft polymerization with atmospheric plasma surface activation.

Polymer layer growth by free radical graft polymerization (FRGP) and controlled nitroxide-mediated graft polymerization (NMGP) of polystyrene was achieved by atmospheric pressure hydrogen plasma surface activation of silicon. Kinetic polystyrene layer growth by atmospheric pressure plasma-induced FRGP (APPI-FRGP) exhibited a maximum surface-grafted layer thickness (125 A after 20 h) at an initi...

Gold-promoted styrene polymerization.

Styrene can be polymerized at room temperature in the presence of equimolar mixtures of the gold(III) complexes (NHC)AuBr3 (NHC = N-heterocyclic carbene ligand) and NaBAr'4, in the first example of a gold-induced olefin polymerization reaction.

Measurement of Dissociation Degree in Pulsed RF Plasma

N atom density is determined in pulsed RF 27 MHz nitrogen plasma at the pressures ranging from 1.5 to 5 torr and effective discharge currents ranging from 80 to 140 mA. From time resolved measurements of fluorescence of second and first positive systems of nitrogen in after-glow the density is calculated using simple kinetic model of nitrogen after-glow. Calculated density of N atoms is in rang...

Kinetic and structural factors in graft polymerization of styrene on polyolefins

Radiation grafting of monomers on polymers is radical polymerization which usually takes place in viscous medium and quite often in a micro-heterogeneous semicrystalline matrix. The role of kinetic and structural factors in the graft polymerization was investigated. Grafting of styrene on polyethylene and polypropylene was initiated by radiation methods (direct irradiation of polymer and monome...
