Starch was preirradiated with cobalt-60 and then allowed to react with mixtures of acrylamide and N,N,N-trimethylaminoethyl methacrylate methyl sulfate (TMAEMA' MS) in a water solution. The graft copolymers resulting were purified and characterized, and the influence of a number of irradiation and reaction variables on graft copolymer composition was determined. Although the reaction of irradia...

The asymmetric unit of the title compound, [Pd(C(12)H(12)NO)(2)], consists of three crystallographically independent half-mol-ecules. Each Pd(II) atom lies on a center of inversion and is four-coordinated by two monoanionic forms of the amino-acryl-aldehyde in a square-planar geometry. In the crystal, adjacent mol-ecules are connected through C-H⋯π and C-H⋯O inter-actions into a three-dimension...

In this study, a novel interpenetrating polymer network (IPN) hydrogel composed of crosslinked sodium alginate and poly(acryl acid) was prepared for transdermal delivery of an antihypertensive drug, prazosin hydrochloride. Due to the reversible swelling behavior of the hydrogels, the synthesized networks can sense the environmental pH change and achieve an oscillatory release pattern. Using dru...

In this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 1,2-phenylenediamine, have been investigated. MWNT-benzimidazole is obtained through MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. These functionalizations have been chosen due to –NH2 and NHCO active sites in MWNT-Amide for future...
