Synthesis and Characterization of Cellulose-graft- Poly (l-lactide) via Ring-opening Polymerization
Cellulose-graft-poly (L-lactide) (cellulose-g-PLLA) was prepared under homogeneous mild conditions. Ring-opening polymerization (ROP) was carried out successfully using 4-dimethylaminopyridine (DMAP) as an organic catalyst in an ionic liquid 1-allyl-3-methylimidazolium chloride (AmimCl). The structure of the polymer was characterized by GPC, H NMR, C NMR, FT-IR, TGA, WAXD, and AFM. The results ...
متن کاملPolymerization Reactions
The tremendous growth of polymer production since the middle of the twentieth century has been intimately connected with the development of new types of catalysts, A notable example in this regard is the field of poly olefin materials, While catalysts are also used in the production of other types of polymers, the properties of most of these materials are not particularly dependent on the type ...
متن کاملSynthesis and Characterization of Cellulose-graft- poly(p-dioxanone) Copolymers via Homogeneous Ring- Opening Graft Polymerization in Ionic Liquids
Cellulose-graft-poly(p-dioxanone) copolymers (cellulose-g-PPDO) were homogeneously prepared via ring-opening graft polymerization (ROP) between p-dioxanone (PDO) and hydroxyl groups of cellulose using the catalyst 4-dimethylaminoptridine (DMAP) in the ionic liquid 1-butyl-3methylimidazolium chloride (BmimCl). Chemical structures and physical properties of the cellulose-g-PPDO copolymers were ch...
متن کاملDevelopment of semi-empirical model for radiochemical reactions.
A mathematical model, which represents the radio-chemical reactions in water, was developed to study the effect of the radio-chemical products on cell killing. The five differential equations were solved using dose rate equation and cell survival as a function of dose was computed. The known chemical rate constants were taken from the literature and unknown constants were determined by curve fi...
