S,s'-bis-(alpha,alpha'-disubstituted-alpha-acetic acid)-trithiocarbonates and derivatives as initiator - chain transfer agent - terminator for controlled radical polymerizations and the process for making the same

摘要

Dithiocarbonate derivatives are disclosed, along with a process for preparing the same. The dithiocarbonate compounds can be utilized as initiators, chain transfer agents and/or terminators in controlled free radical polymerizations. The dithiocarbonates can be used to produce polymers having narrow molecular weight distribution. Advantageously, the compounds of the present invention can also introduce functional groups into the resulting polymers. The dithiocarbonate compounds have low odor and are substantially colorless.
