Novel biobased epoxy resins were prepared from waste vegetable oil by epoxidation using hydrogen peroxide in acetic acid. Biobased epoxy resins were prepared by reaction of acid hardeners such as citric acid (B1), tartaric acid (B2), succinic anhydride (B3) and sebacic acid (B4) with epoxydised waste vegetable oil. The intrinsic viscosities were in the range of 0.06 to 0.70 (dL/g) and thermally stable up to 350°C. Solution cast thin films are transparent except B4. The resin films were completely biodegraded by using bacterial granules (made up of bacterial consortia) within 14-135 days. The resin [B1] was found to be biocompatible based on blood clotting studies.

AbstractWe present the optical and photochromic properties as well as surface quality of thin films of the methacrylic copolymers containing 2-methylquinoline and quinoline azo-dyes in side chain. The extinction coefficient and refractive index were determined using spectroscopic ellipsometry combined with transmittance measurements. Photo-responsive behavior was investigated by determination of trans–cis photoisomerization rates under irradiation with unpolarized 365 nm light. We found that optical properties as well as photoisomerization rates of investigated polymers are dependent on the presence of a methyl substituent in the 2nd position of the quinoline moiety. The quality of the thin films was examined using Atomic Force Microscopy measurements.
