Preparation and Characteristics of Microcapsules containing Water-Absorbent Polymer

Preparation of a Water-Soluble Fluorescent Polymer

A fluorophore-enriched polymer was synthesized through modification of a kind of copolymer by fluorescein isothiocyanate (FITC). The copolymer was obtained by batch emulsion polymerization of t-butyl acrylate (t-BA) and an amino-containing monomer M2, which was produced in our laboratory. According to various characterizations, such as gel permeability chromatography (GPC), H-NMR, fluorescence ...

Preparation of the Water-Soluble Pyrene-Containing Fluorescent Polymer by One-Pot Method

A new water-soluble pyrene-containing fluorescent polymer, 1-{31-S-[poly(acryloyl ethylene diamine hydrochloride)-21-methyl propionic acid]}propionyloxy hexyloxy pyrene (P3) with defined structure, was designed and synthesized using the click reaction between thiol and a carbon-carbon double bond. The intermediate products P1 (S-1-dodecyl-S1-[poly(N-Boc-acryloyl ethylene diamine)-21-methyl prop...

Evaluation of Relative Membrane Permeability of Sorghum (Sorghum bicolor) Affected Super Absorbent Polymer and Water Deficit Conditions

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...

Preparation and Characterization of Novel Microcapsules

Multiresidue analysis of pesticides in vegetables and fruits using a high capacity absorbent polymer for water.

A single extraction and a single clean-up procedure was developed for multi-residue analysis of pesticides in non-fatty vegetables and fruits. The method involves the use of a high capacity absorbent polymer for water as a drying agent in extraction from wet food samples and of a graphitized carbon column for clean-up. A homogeneously chopped food sample (20 g) and polymer (3 g) were mixed to a...
