Macromonomers formed by chain transfer catalysis polymerization methods may be decolorized by selective extraction and/or adsorption. The dimers and trimers formed during the polymerization reaction are also removed from the macromonomer mixture so that the remaining mixture has a very low optical density and a desirable degree of polymerization.
Il est possible de décolorer par extraction et/ou adsorption sélective les macromonomères qui résultent d'une polymérisation par catalyse à transfert de chaîne. Les dimères et les trimères formés durant la réaction de polymérisation sont également extraits du mélange de macromonomères, pour conférer au mélange résultant une très faible densité optique et le degré de polymérisation voulu.
