Synthesis of (multi)block copolymers using reversible addition–fragmentation chain transfer (RAFT) polymerization generally suffers from the limitation that order blocks must be considered. Herein, syntheses block by RAFT trithiocarbonate species are conducted as solution, miniemulsion, and emulsion polymerizations to demonstrate issue monomer for styrene butyl methacrylate can largely overcome...

The objective of the study was to formulate controlled release matrix tablets of losartan Potassium by using a combination of hydrophilic synthetic polymer like poly (ethylene oxides) and natural gums like xanthan gum, karaya gum and guar gum. A combination of synthetic hydrophobic polymers like methacrylates with synthetic hydrophilic polymer like poly (ethylene oxide) was also used in the pre...

A thin and compact mixed matrix membrane containing CAU-1-NH2 and the poly(methyl methacrylate) polymer has been originally synthesized. The as-prepared membrane exhibits high permeability of H2 and excellent H2/CO2 selectivity.

Previous investigations on solid state polymerization are reviewed, and a few examples of new experimental results are added. Radiation-induced polymerizations of methyl methacrylate in the supercooled liquid phase, and of cyclohexene oxide in the plastic crystalline phase, have been examined. Polymerizations of acrylamide and N-vinylcarbazole were investigated on a solid surface with initiatio...
