  Tertiary nitrogen-containing chain-extended epoxy resins, capable of forming stable aqueous emulsions, may be produced by chain-extending an epoxy resin using a tertiary nitrogen containing ether or ester polyol for example, particularly, polycaprolactone which has been polymerisation initiated by a tertiary amine polyol such as N-methyl diethanolamine. The corresponding amine salt is formed by treatment with an acid for example acetic acid and the resulting cationic polymer may be dispersed in water to form a cationic emulsion capable of being coated onto a substrate by electrodeposition. The chain extended resins, by virtue of their content of free epoxy groups are also usable for cross-linking and other uses.

  可通过使用含叔氮的醚或酯多元醇（例如，特别是聚己内酯）对环氧树脂进行扩链，生产出能够形成稳定水性乳液的含叔氮扩链环氧树脂，聚己内酯是由叔胺多元醇（例如 N-甲基二乙醇胺）引发聚合反应的。相应的胺盐可通过酸（如醋酸）处理形成，由此产生的阳离子聚合物可分散在水中，形成阳离子乳液，并可通过电沉积涂覆在基底上。链延伸树脂由于含有游离环氧基团，也可用于交联和其他用途。
