Grafting of Acrylamide to Low Density Polyethylene During Melt Processing
Acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. Effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. FTIR studies revealed that the degree of grafting increased by an increase in acrylamide concentration. Maximum grafting was obtained at 7 mi...
متن کاملMelt Rheology of Poly(Lactic Acid)/Low Density Polyethylene Polymer Blends
In this work, rheological properties of poly(lactic acid) (PLA), low density polyethylene (LDPE) polymer blends were investigated in the molten state. The experiments were carried on a capillary rheometer. The effect of shear stress, temperature and blending ratio on the flow activation energy at a constant shear stress and melt viscosity of the blends are described. The results showed that the...

متن کاملInteraction of Tetradecyltrimethylammonium Bromide with Poly(acrylic acid) and Poly(methacrylic acid). Effect of Charge Density
The effect of polymer chalge density on the interaction of tetradecyltrimethylammonium brolnide <TrAB) with poly(acrylic acid) (PAA) and poly(methacrylic acid) (PMA) has been investigated usmc a surfactant-sensitive solid-state membrane electrode. The experimental results indi~te that the intenction with PAA begins at about the same equilibrium TTAB concentration wben the degree of ionization (...
متن کاملPoly(acrylic acid)–Poly(vinyl alcohol) Copolymers with Superabsorbent Properties
Biodegradable polyacrylates were produced by a series of novel copolymerization and/or crosslinking techniques using poly(vinyl alcohol) (PVA) moieties modified by the incorporation of olefinic structures. PVA was modified by a tosylation and/or detosylation reaction. The functionalized PVA was copolymerized and/or crosslinked with acrylic acid or its partially neutralized form to give crosslin...
