Molecular weight truncation and color control in macromonomers |
摘要 |
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.
