Title:
原子移動ラジカル重合を使用して調製されるエポキシ官能性ポリマーを含む熱硬化性組成物
Document Type and Number:
Japanese Patent JP3586426
Kind Code:
B2
Abstract:
A thermosetting composition is provided comprising:(a) a crosslinking agent having at least two functional groups that are reactive with epoxides; and(b) a non-gelled, epoxy functional polymer prepared by atom transfer radical polymerization, in the presence of an initiator having at least one radically transferable group. The polymer contains at least one of the following polymer chain structures:wherein M is a residue, that is free of epoxy functionality, of at least one ethylenically unsaturated radically polymerizable monomer; G is a residue, that has epoxy functionality, of at least one ethylenically unsaturated radically polymerizable monomer; p and q represent average numbers of residues occurring in a block of residues in each polymer chain structure; and p, q, and x are each independently selected for each structure such that the epoxy functional polymer has a number average molecular weight of at least 250. Also provided by the present invention are methods of coating a substrate using compositions of the present invention and substrates coated by such methods, as well as color-plus-clear composite coatings.
