  This invention is directed to certain tetrahydrocarbyl phosphonium phenoxide salts. These compounds have the structural formula: Each R independently is a hydrocarbyl or inertly substituted hydrocarbyl, X is a phenoxide anion and m is the valence of the anion X. The phenoxide anion X is a conjugate base of a polyhydric phenol bearing from 2 to 6 nuclear hydroxyl groups and having from 6 to 30 carbon atoms. These phosphonium phenoxide salts optionally may be complexed with a polyhydric phenol or with a tetrahydrocarbyl phosphonium hydroxide salt. The compounds of this invention are suitable as catalysts for reacting vicinal epoxy groups with phenols, carboxylic acids and carboxylic anhydrides. These compounds are also suitable for preparing precatalyzed epoxy resins and precatalyzed polyhydric phenols. When these compounds are employed as catalysts in the advancement reaction of the diglycidyl ether of bisphenol A with bisphenol A, epoxy resins having weight average molecular weights over 100,000 units have been demonstrated.

  Extremely rapid ambient curing of polyepoxide resins and mixtures of polyepoxide resins and polyacrylate esters is achieved by use of a curing system composed of at least one polymercaptan and at least one catalytic co-curing agent which is the condensation product of: (a) aliphatic amine or substituted aliphatic amine containing at least one primary aliphatic amine group where the aliphatic moiety is ethylene or greater with (b) at least one amino acid, its corresponding lactam or other amide forming derivative. Optionally, known Lewis Base catalysts for the epoxy/ mercaptan reaction, such as tertiary amines, may also be used.

  通过使用由至少一种聚合物硫醇和至少一种催化助固化剂组成的固化体系，可实现聚环氧树脂以及聚环氧树脂和聚丙烯酸酯混合物的极速常温固化。 催化助固化剂是下列物质的缩合产物：(a) 脂肪族胺或含有至少一个伯脂肪族胺基团的取代脂肪族胺，其中脂肪族分子为乙烯或更大的乙烯基；(b) 至少一种氨基酸、其相应的内酰胺或其他酰胺形成衍生物。 也可选择使用已知的环氧/硫醇反应路易斯碱催化剂，如叔胺。

• A process for preparing advanced epoxy resins employing tetrahydrocarbyl phosphonium salts as catalysts and advanced epoxy resins prepared by the process
  申请人：THE DOW CHEMICAL COMPANY

  公开号：EP0117562A2

  公开（公告）日：1984-09-05

  This invention is directed to a process for preparing an advanced epoxy resin by reacting (a) a compound bearing an average of more than one vicinal epoxide group per molecule with (b) a polyhydric phenol or thiophenol, in the presence of a catalytic amount of a tetrahydrocarbyl phosphonium salt. The invention is characterized in that the reaction is conducted under conditions such that the reaction and exotherm temperature does not exceed 175 °C and the reaction medium is essentially anhydrous. These conditions are shown to prevent significant deactivation of the catalyst. Advanced epoxy resins produced by this process are generally less colored and have epoxy equivalent weights closer to the theoretical values than prior art resins produced in the conventional manner using phosphonium salts as catalysts. The process of this invention also includes the optional step of adding a sufficient amount of a phosphonium ylid quenching agent to selectively deactivate the catalyst without substantial reaion with the advanced epoxy resins.

  本发明涉及一种制备高级环氧树脂的工艺，在催化量的四氢羰基鏻盐存在下，(a)一种平均每分子含有一个以上副环氧基团的化合物与(b)一种多水合苯酚或噻吩酚反应。本发明的特点是，反应是在反应温度和放热温度不超过 175℃，反应介质基本无水的条件下进行的。事实证明，这些条件可防止催化剂严重失活。与使用鏻盐作为催化剂以传统方式生产的现有技术树脂相比，本工艺生产的高级环氧树脂一般着色较少，环氧当量重量更接近理论值。 本发明的工艺还包括一个可选步骤，即加入足量的膦酰基淬灭剂，以选择性地使催化剂失活，而不会对高级环氧树脂产生实质性的影响。
