标题:Synthesis of dithioester chain transfer agents and use of bis(thioacyl) disulfides or dithioesters as chain transfer agents
发明人：RIZZARDO ENZIO; THANG SAN HOA; MOAD GRAEME
权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG
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.

摘要:Methods of preparing macromonomers, e.g., single- or double-tailed macromonomers, using radical polymerization of a first monomer in solution or in an emulsion are described. Methods of using the macromonomers in the preparation of multigraft copolymers are also described. For instance, the macromonomer prepared by radical polymerization can be used in an emulsion copolymerization with a second monomer to form a random multigraft copolymer. The random multigraft co-polymers can be superelastomers.
