this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

Both chitosan and polylactide/polyglycolide have good biocompatibility and can be used to produce tissue engineering scaffolds for cultured cells. However the synthetic scaffolds lack groups that would facilitate their modification, whereas chitosan has extensive active amide and hydroxyl groups which would allow it to be subsequently modified for the attachment of peptides, proteins and drugs....

Current research is moving towards iron and ammonia elimination from groundwater. Here, we are using a poly acrylic–poly acrylamide hydrogel that grafted with 3-chloroaniline. This copolymer was synthesized by addition polymerization technique. The effects of agitation time, dosage adsorbent temperature on the removal process sensitivity were investigated. described experientially theoretically...

To modify the surface properties of inorganic materials, we successfully covalently attached a stable monolayer, with high grafting density, of N,N(diethyl)dithiocarbamoylbenzyl(trimethoxy)silane on the surface of silicon wafers and glass substrates, thereby creating a surface-grafted photoinitiator for “living” free radical photopolymerization. The surface-grafted initiators were utilized for ...

The goal of this research is to prepare novel amphiphilic graft copolymers (nonionic) based on hydrophilic poly (ethylene glycol) methyl ether (mPEG) and hydrophobic methacrylate (MMA) at room temperature pressure. To generate P(mPEG-g-MMA) grafts, was synthesized grafted with varied ratios in the existence benzoyl peroxide as an initiator utilizing a macro-free radical procedure under effect h...
