Graft Polymerization of Acrylonitrile onto Starch-Coated Polyethylene Film Surfaces
Starch-coated polyethylene (PE) films were prepared by immersing PE in a hot, jet cooked solution of starch. They were allowed to react with acrylonitrile (AN) in the presence of ceric ammonium nitrate initiator, and the graft polymerization that occurred produced starch-g-polyacrylonitrile (PAN) coatings that contained about 25 wt % grafted PAN. The starch-g-PAN coatings tightly adhered to the...
متن کاملTretinoin and Benzoyl Peroxide
A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...
متن کاملPAL study of graft polymerization of MMA on polyethylene
PAL measurements were used to study the process of graft polymerization of methyl methacrylate (MMA) to low density polyethylene (LDPE). When the monomer was just sorbed to LDPE, both I, and z, were increased. When MMA was grafted to LDPE, on the other hand, they were decreased. These contrasting results suggests usefulness of the PAL method to study the micro-structures of polymers. Introducti...
متن کاملRadiation graft post-polymerization of sodium styrene sulfonate onto polyethylene
Post-irradiation grafting of sodium styrene sulfonate (SSS) in the presence of acrylic acid (AA) has been investigated on polyethylene (PE) pre-exposed to gamma radiation at room temperature in the air. Special attention was paid to the effect of low molecular weight salt additives on the kinetics of graft copolymerization of SSS and AA. The presence of SSS links in the grafted PE copolymers wa...
متن کاملAnalysis of benzoyl-peroxide and formaldehyde as dental allergens by FT-SPR method
In parallel with the appearance of new dental materials the number of induced allergic diseases increases. Based on this fact more sensitive detection of allergens is major importance. The Fourier-Transform Surface Plasmon Resonance (FT-SPR) is a sensitive, broadly applicable real-time method for analysing thin layers of materials on gold surfaces. FT-SPR measurement is performed at a fixed ang...
