Monofilament Mesh

In this study, a commercial and fully flexible monofilament mesh has been used for the deposition of a thermosensitive hydrogel, generated by graft copolymerization of N-isopropylacrylamide (NIPAAm) and N,N′-methylene bis(acrylamide) (MBA) monomers.

Acrylamide Monomer

The synthesis of superabsorbent polymer with Carboxymethyl cellulose using ceric ammonium nitrate (CAN) initiated acrylamide (AA) monomer through a solution based graft copolymerization has been conducted. The characterizing studies were performed using Fourier transform infrared (FTIR) spectroscopy, Atomic force microscopy (AFM) and swelling studies. FTIR spectra established crosslinked polymeric network structure of hydrogels through graft copolymerization reaction between CMC and acrylamide indicating incorporation of acrylamide monomer resulting the formation of carboxamide group (>C=O). AFM showed the surface morphology or properties of superabsorbent. The hydrophilic properties of the superabsorbent were identified by the swelling percentage or degree of swelling.

Application Scope

Cellulose is the most abundant, renewable, and biodegradable natural resource on the earth. Grafting copolymerization technique is one of the key methods to widen the application scope of cellulose. This paper concerned with the recent progress and application of living/controlled radical graft polymerization techniques such as NMP, ATRP, and RAFT in the grafting modification of cellulose. The advantages and disadvantage of them were also reviewed.

Isopropenyl Acetate

Radiation-induced graft copolymerization of vinyl acetate (VAC) and isopropenyl acetate (PAC) onto isotactic polypropylene (IPP) has been studied. The percentage of grafting was calculated for various reaction parameters, and the optimum conditions for attaining the maximum percentage of grafting were determined. Maximal achieved extents of grafting are 39% and 29% for VAC and PAC, respectively. The reactivity of the two monomers with respect to grafting is discussed.
