    • A method of making a copolymer composition containing a copolymer, which includes the steps of (a) providing a donor monomer composition that includes an isobutylene type monomer; (b) mixing the donor monomer composition with an ethylenically unsaturated monomer composition that includes one or more ethylenically unsaturated acceptor monomers, and is substantially free of maleate type monomers and fumarate type monomers, and (c) polymerizing the mixture resulting from step (b) in the presence of a free radical polymerization initiator. The polymerization is carried out in the substantial absence of Lewis acids and/or transition metals. The isobutylene type monomer is present at a molar excess of at least 10 mol % based on the molar concentration of monomers in the ethylenically unsaturated monomer composition. The ethylenically unsaturated acceptor monomers are present in an amount of at least 15 mol % of the total monomer composition.
    • 一种制备含有共聚物的共聚物组合物的方法,其包括以下步骤:(a)提供包含异丁烯型单体的供体单体组合物; (b)将供体单体组合物与包含一种或多种烯键式不饱和受体单体的烯属不饱和单体组合物混合,并且基本上不含马来酸盐型单体和富马酸盐型单体,和(c)将由步骤(b)得到的混合物聚合, 在自由基聚合引发剂存在下进行。 基本上不存在路易斯酸和/或过渡金属进行聚合。 基于烯属不饱和单体组合物中单体的摩尔浓度,异丁烯型单体的摩尔过量为至少10摩尔%。 烯属不饱和受体单体的存在量为总单体组合物的至少15摩尔%。

    • Disclosed are thermosetting compositions which are comprised of a resinous phase dispersed in an aqueous medium, the resinous phase comprising (a) an ungelled active hydrogen group-containing polymer which contains amine salt groups, the polymer having been prepared by atom transfer radical polymerization in the presence of an initiator having at least one radically transferable group, and (b) a curing agent having at least two functional groups which are reactive with the active hydrogen groups of (a). The active hydrogen group-containing polymers of the thermosetting compositions, which are prepared by atom transfer radical polymerization, have narrow molecular weight distributions and well-defined, specifically tailored polymer architecture which can provide enhanced crosslink density and dispersibility of the thermosetting compositions. Also disclosed is a method of electrocoating a conductive substrate using the thermosetting compositions of the invention, and a substrate coated by this method.
