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...

CO2 geo-storage in basaltic formations has recently been identi?ed as a viable option to rapidly dispose large quantities of , hence mitigating anthropogenic emissions. However, it shown that basalt is weakly water-wet or intermediate-wet at typical storage conditions, which reduces capillary trapping capacities and increases lateral vertical spreading the plume; these effects increase project ...

The formation of membranes from two systems has been studied. In the system polyurethanedimethylformamide-water, the mechanism for the formation of the sponge-like structure proves to be a liquid-liquid phase separation with nucleation and growth of the diluted phase. This mechanism has been confirmed for the system modified polystyrene-polyisoprene-polystyrene/ o-dichlorobenzene/(methanol-wate...
