Synthesis and Characterization of Cross-Linked Tri-Polymers of Poly Acrylic Acid as Water Thickening Agents

Abstract

A cross-linked poly acrylic acid tri-polymer is successfully synthesized by batch charging polymerization of poly allyl tris buffer, di-vinyl benzene and acrylic acid and this new method is profitable in terms of reducing the toxicity, faster, purity and cheaper than available methods. The morphological structure of the synthesized polymer is studied by SEM and the characteristic functional groups of the synthesized polymers are identified using FTIR. TGA and DSC techniques were employed to study their thermal characterization.

Synthesis and Characterization of Some New Biologically Active Pyrimidine Derivatives

“…In modern years, pyrimidine and dihydropyrimidines have been in an important position in natural and synthetic organic chemistry, due to their wide range of biological activities, such as antibacterial, antiviral, antihypertensive and antitumor effects and their effects as calcium channel blockers. [1][2][3][4][5][6][7][8][9][10][11][12][13] The development of efficient and environmentally acceptable synthetic methods is an important task of modern chemistry. Conventional organic syntheses are generally based on homogeneous catalysts.…”
