    • Disclosed is a new partial capping synthesis wherein resinous mixtures containing controlled amounts of phenolic hydroxyl and/or mercapto functionality, and aliphatic hydroxyl functionality are synthesized. Such synthesis comprises providing one or more resins which in total contain aliphatic primary and/or secondary hydroxyl functionality and oxirane functionality. A single resin or blend of resins may provide the requisite functionality. The one or more resins then are reacted with a carboxyl-functional capping agent bearing phenolic hydroxyl functionality and/or mercapto functionality. This reaction is conducted under reaction conditions and for a time such that the carboxyl functionality of the capping agent selectively reacts with the oxirane functionality of the one or more resins to produce a resinous product containing aliphatic hydroxyl functionality and containing phenolic hydroxyl functionality and/or mercapto functionality.
    • 公开了一种新的部分封端合成法,其中合成含有受控量的酚羟基和/或巯基官能团和脂族羟基官能团的树脂混合物。 这种合成包括提供总共含有脂族伯和/或仲羟基官能团和环氧乙烷官能团的一种或多种树脂。 单一树脂或树脂混合物可提供必要的功能。 然后使一种或多种树脂与具有酚羟基官能团和/或巯基官能团的羧基官能性封端剂反应。 该反应在反应条件下进行一段时间,使得封端剂的羧基官能团选择性地与一种或多种树脂的环氧乙烷官能团反应,以制备含有脂族羟基官能团并含有酚羟基官能团和/或巯基的树脂产物 功能。
