DSC

In this research, we discuss the variations in producing new composite materials using natural row material wood flour (60%), as a primary ingredient, eco-friendly binder poly[(trimethoxy)4-vinylphenethyl)]silane (3, 5, and 30%) and styrene with different degrees of silylation (25 and 27%), under constant pressure and at the various temperatures. The composites were obtained via hot pressing. In addition to the binder, various additives, antioxidants, and antipirene were employed in the manufacturing process.

According to DSC and EPR data kinetics of formation of simultaneous semi-interpenetrating polymer networks based on crosslinked polyurethane and linear polymethylmethacrylate with 50:50 and 70:30 ratio obtained in the presence of 3d-metal chelates depends on type of metal. On the other hand system composition determines polyurethane or polymethylmethacrylate selection during formation of complexes with metal-diketonates.

The melting behavior of polypropylenes of different chemical structure (isotactic homopolypropylene, propylene-based block and random copolymers and maleic anhydride grafted polypropylene) was studied by differential scanning calorimeter (DSC) and optical microscopy. Melting behavior and the crystal structure of polypropylene and its copolymers were observed depending on the crystallization rate, chemical nature of co-monomer unites and regularity of co-monomer units arrangement in the polypropylene main chain.
