摘要： This invention relates to the controlled molecular weight production of macromonomers and polymers with terminal conjugated double bonds from starting monomers including, but not limited to, substituted butadienes. The terminal diene end thus produced is also a potential reaction site for further polymerization or functionalization. The molecular weight is controlled by use of Co chain transfer catalysts and appropriate process conditions.

摘要： This invention relates to a method for preparing compositions comprising terminally unsaturated polymers of low molecular weight, referred to as oligomers or macromonomers. In particular, a first oligomer composition is obtained by free radical polymerization of a reaction mixture comprising monomers. Terminally unsaturated oligomers in the first oligomer composition, or a selected portion of the composition, are reinitiated into free radicals in order to continue their oligomerization to a desired endpoint. The process is useful for preparing an oligomer composition having a controlled degree of polymerization. The process is also useful for preparing block copolymers. Such oligomer compositions or block polymers are useful for preparing engineered or structured polymers used in making various end products, including plastics, coatings, films, and dispersants.

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.

摘要： This invention relates to a method by which olefinically-unsaturated organic molecules, which are otherwise nonpolymerizable, may be homopolymerized or copolymerized with conventional monomers through the use of cobalt chain transfer catalysts. The resulting macromonomers contain one terminal functional group and a terminal double bond on the other end of the chain.
