## Abstract Polyesterβbased polyurethanes with embedded nanosilica particles were prepared. The viscosity of polyester resins without and with nanosilica was determined by rheoviscometry. The morphology and mechanical and optical properties of the polyurethane coatings were studied intensively with

Stabilization of the bis(ΞΌ-oxo)dicopper(III) intermediate is achieved by using a bidentate N-donor ligand with pendent indole rings: N,N-bis[(3-indolyl)methyl]-N-[(2'-pyridyl)methyl]amine (BIP). The intermediate decomposes to give products arising from N-dealkylation and a product with a spiro ring
The effect of processing temperature and time on the Btype crystallinity of thermoplastic starch was studied by recording X-ray diffractograms of conditioned, compression molded starch systems containing glycerol and water as plasticizers at a ratio of 100 : 30 : 56 (w/w/w). Initial recrystallizatio
