Copolymerization of Vinyl Chloride by Organometallic Compounds
ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...
متن کاملMutagenicity and metabolism of vinyl chloride and related compounds.
The various adverse biological effects of vinyl chloride appear to be dependent upon the metabolic conversion of this compound into chemically reactive metabolites. The metabolism of vinyl chloride in mammals and in man, including the formation of monochloroacetic acid and some identified sulfur conjugates is reviewed. Hepatic microsomal mixed function oxidases from rats, mice, and humans were ...
متن کاملWhen CMRP met alkyl vinyl ketone: visible light induced living radical polymerization (LRP) of ethyl vinyl ketone (EVK).
Photo responsive polyethyl vinyl ketone (PEVK) and various block copolymers were prepared through the visible light induced cobalt mediated radical polymerization (CMRP) process. The first order kinetics and linear increase in molecular weight with conversion demonstrated a well-behaved system. Chain extension experiments showed the retention of the living end of PEVK.
متن کاملPlasticization of gas separation membranes*
For the investigation of the plasticizing effect of carbon dioxide on polymers used for gas separation membranes new experimental methods have been developed that measure the sorption kinetics as well as the dilation kinetics. Comparing dilation and sorption kinetics at low and elevated pressures gives information about different types of swelling behaviour depending on the pressure level. Volu...
متن کاملPreparation of Alkyl Alkynyl Sulfones and Cyclic Vinyl Sulfones from Alkynyl(aryl)iodonium Salts.
The reaction of alkyl sulfinates with alkynyl(aryl)iodonium salts provides a facile access into otherwise difficult to obtain alkyl alkynyl sulfones and cyclic vinyl sulfones via 1,2-rearrangement or 1,5-CH insertion, respectively. In benzyl sulfinates, 1,5-CH insertion is not possible, so addition to the aromatic ring occurs, followed by ring expansion to generate novel bicyclic sulfones.
