    • The present invention is directed to a method for producing a copolymer and a copolymer product of the method. The copolymer is prepared by a controlled radical polymerization process, typically an atom transfer radical polymerization process, in which polymerizable alkene monomers are polymerized in the presence of a halogenated polyolefin macroinitiator. The copolymer product of this process is useful in a film-forming composition that adheres strongly to polyolefinic substrates and to which non-polyolefinic film-forming compositions strongly adhere. The copolymer can be applied to a substrate in an adhesion-promoting layer or can be incorporated into a film-forming composition, such as a primer, that contains additional resinous compounds.
    • 本发明涉及一种制备该方法的共聚物和共聚物的方法。 共聚物通过受控自由基聚合方法制备,通常是原子转移自由基聚合方法,其中可聚合烯烃单体在卤代聚烯烃大分子引发剂存在下聚合。 该方法的共聚物产物可用于强烈粘附到聚烯烃基材上并且非聚烯烃成膜组合物强烈粘附的成膜组合物。 共聚物可以施加到粘合促进层中的基材上,或者可以加入到含有另外的树脂化合物的成膜组合物如引物中。

    • Provided are block copolymers containing at least two blocks are provided and comprise: (a) a first block containing residues of at least one first ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., 2-ethylhexyl methacrylate, and, optionally, a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer, e.g., hydroxypropyl methacrylate; and (b) a second block containing residues of at least one second ethylenically unsaturated radically polymerizable monomer that is free of hydroxy functionality, e.g., iso-butyl methacrylate, and, optionally, a minor amount of at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer. The calculated Tg of the second monomer of the block copolymer is at least 20 DEG C greater than the calculated Tg of the first monomer. Also provided are thermosetting coating compositions that contain the block copolymers as flow additives.
