Various radical polymerizations of glycerol-based monomers

Magnetic Levitation To Characterize the Kinetics of Free-Radical Polymerization.

This work describes the development of magnetic levitation (MagLev) to characterize the kinetics of free-radical polymerization of water-insoluble, low-molecular-weight monomers that show a large change in density upon polymerization. Maglev measures density, and certain classes of monomers show a large change in density when monomers covalently join in polymer chains. MagLev characterized both...

Lipase-Catalyzed Polymerization of Glycerol and Dicarboxylic Acids in an Organic Medium

Lipases from different sources catalyze the polyesterification of glycerol and several dicarboxylic acids in presence or organic solvents Introduction Enzymatic polymerizations are receiving much attention as a new method for polymer production since biocatalysis is expected to generate environmentally acceptable properties such as biodegradability and biocompatibility [1]. The opportunities av...

Metal-catalyzed radical polyaddition as a novel polymer synthetic route.

A new class of polymerizations was developed via metal-catalyzed C-C bond forming radical polyaddition; the monomers were designed to have a reactive C-Cl bond, which can be activated by the metal catalysts to generate a carbon radical species, along with a C=C double bond, to which the carbon radical generated from another molecule adds to form a C-C backbone polymer with an inactive C-Cl pend...

Metal-free atom transfer radical polymerization.

Overcoming the challenge of metal contamination in traditional ATRP systems, a metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported. Polymerization of vinyl monomers are efficiently activated and deactivated with light leading to excellent control over the molecular weight, polydispersity, and chain ends of the resulting polymers. Signifi...
