摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

权利人:VIFOR INT AG
摘要:The present invention relates to novel synthesis methods of methyl 2-fluoroacrylate (MFA) which is a key precursor for the production of Veltassa® (Patiromer). The methods according to the invention are conducted by reacting an α-substituted β-hydroxy propionic acid derivative (I) via one or more intermediate steps involving one or more α-, β-substituted propionic acid derivatives (II) to obtain MFA (III).

标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人：URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.
