Реферат: Abstract of the Disclosure An improved process for the preparation of cationic resins derived from polyepoxides is disclosed. Typically, the process comprises contacting the polyepoxide with particular polyether polyols and heating the two together to form a resin which may then be reacted with a cationic base group former such as an amine and acid. Aqueous dispersions of the cationic resins prepared by the improved process are useful for coating applications, particularly cationic electrodeposition. They exhibit good low temperature cure response and the cured coatings have good physical properties such as resistance to water, detergent and salt spray corrosion.
