A novel approach has been adopted for synthesizing composite polymer electrolytes with a blend of atactic poly(methyl methacrylate) (a-PMMA) and isotactic PMMA (i-PMMA) owing to their ability to form stereocomplex structures, especially double helix like structures. Nanocomposite polymeric electrolytes based on gel polymeric electrolyte (GPE) consisting of stereocomplex PMMA, propylene carbonat...

We report for the first time selective hydrogenation of 1,3-butadiene to butene using formic acid as hydrogen source with 1 wt% Pd/carbon in a continuous flow reactor.

Poly( 1-butene) (PB) crystallizes from the melt in a metastable modification II (mod. II) which slowly transforms into the stable modification I (mod. I). X-ray wide angle (WAXS) measure­ ments show that in mod. I the size of the microparacrystallites (mPC’s) in chain direction, Z>oi2 * the polydispersity gj> of the size distribution in this direction, the lateral size D u o and the paracrystal...
