1. Crosslinking of Ethylene Copolymers
Abstract : The chemical reactions taking place when crosslinking poly(ethylene-co-vinyltrimethoxysilane) (EVS) have been studied. Films of EVS were stored in water at 90 °C or treated at processing temperatures in a tubular oven. The different chemical groups involved in the reactions were then followed by FTIR after different treatment times. READ MORE

2. Durable Polysulfones with Densely Sulfonated Segments for Highly Proton Conducting Membranes
Abstract : Fuel cells are considered as a promising alternative environmentally benign power source to the existing ones depending on petroleum oil. Especially, proton-exchange membrane fuel cells (PEMFCs) have been intensively developed during the last decade because of their wide application windows including various portable, stationary and transportation applications.

4. Functional Copolymers of Polyvinylpyrrolidone
Abstract : In many ways, polyvinylpyrrolidone (PVP) has a unique combination of chemical and physical properties. Unlike most polymers it is soluble in water as well as a number of organic solvents. PVP also has excellent film forming properties, outstanding chemical stability, complexing ability, low toxicity, and good adherence to many different substrates. READ MORE
