权利人:UNIV TENNESSEE RES FOUND
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.
