Alcid Bamboo
Abstract: AbstractNatural bamboo is one of the fastest growing plants, with maturity cycle of 3–4 year, thus making highly attractive natural renewable resource compared to hardwood. This bamboo can replace timber in many applications, but their mechanical property differs with species, age, climatic factor, moisture content and different height of culm. Due to this the natural bamboo can be replaced by synthetic one which are man-made and also known as engineered …

Application of Poly (o-anisidine) Nanocomposite and PET Recycled Polyester Amide in Anticorrosive Coatings
Abstract: AbstractPolyethylene terephthtalate (PET) was depolymerized through aminolysis technique using ethanolamine into Bis (2-hydroxyethylene) terepthalamide (BHETA). BHETA is having hydroxyl functionality present in it so it is used as monomer and treated with sebacic acid using sulphuric acid as a catalyst. The synthesized resin having ester linkage present in it along with that in BHETA, amide linkage is also present hence it can be called as polyesteramide resin. This synthesized carboxyl …

Determination of Accurate Molecular Weights of Cationic Polyacrylamide Polymers through Advanced Gel Permeation Chromatography Triple Detection Technique
Abstract: AbstractGel permeation chromatography along with refractive index detector or UV detector provides relative molecular weight information along with PDI with respect to standard used. If standards are of different nature than sample such relative results just are used to compare polymers and co-polymers among themselves. These detectors fail to reveal information about other important polymer characters like size of polymer in solution (hydrodynamic volume), branching pattern and intrinsic viscosity which …

ESR Evidence of Growing Unsaturation in -Irradiated Poly (Vinyl Alcohol)
Abstract: AbstractFree radicals present in gamma irradiated PVAL subjected to different degrees oxidation are identified using ESR spectroscopy. The observed ESR spectra are analysed by computer simulations. Gamma irradiated PVAL immediately after irradiation possess ~CH2–CH–CH2~ type free radicals (I). Upon oxidation the free radicals transform to ~CH2–CH=CH–CH2~ (II) highly oxidized PVAL consist ~CH2–C=O (III) type free radicals. The results suggest that radical (I) is precursor to radicals (II) and (III). Oxidation …
