Abstract
Low molecular weight crosslinking agents useful in coatings based on esters of acrylamidoglycolate ethers are disclosed. The copolymeric crosslinking agents of the invention are prepared by copolymerizing a reactive acrylamidoglycolate monomer such as MAGME.RTM. methyl acrylamidoglycolate methyl ether with comonomers such as methyl methacrylate or butyl acrylate. The process of preparing the copolymeric crosslinkers of the invention makes use of chain transfer agents to limit the molecular weight of the crosslinking agents to 10,000 or less.
