• A process to induce rapid curing of a copolyester resin with epoxide compounds
  申请人：THE GOODYEAR TIRE & RUBBER COMPANY

  公开号：EP0056356A1

  公开（公告）日：1982-07-21

  A copolyester resin having modified carboxyl terminated ends is disclosed, as well as the method for making and using that compound with epoxide curing compounds in powder coating resins for substrates. The polymerization of the copolyester resin contains a reactor compounding stage which permits the reaction of the carboxyl termini with a curing reaction catalyst prior to any compounding or mixing of the modified copolyester resin with the epoxide curing compounds. The modification to these end groups of the copolyester resin creates activated termini which, although stable of themselves, react more rapidly, when the modified copolyester resin is compounded with the epoxide curing compounds and subsequently heated on the substrate, than with the conventional introduction of the epoxide catalyst during final compounding. Alteration of the curing parameters of the modified copolyester resin with the epoxide curing compounds imparts greater impact strength and better leveling properties at temperatures between 300 ° F. and 450 °F.

  本发明公开了一种具有改性羧基末端的共聚酯树脂，以及在底材粉末涂料树脂中制造和使用该化合物与环氧化物固化化合物的方法。共聚聚酯树脂的聚合过程包含一个反应器复合阶段，该阶段允许羧基末端与固化反应催化剂发生反应，然后再将改性共聚聚酯树脂与环氧化物固化物进行复合或混合。对共聚酯树脂的这些末端基团进行改性可产生活化端基，虽然这些端基本身是稳定的，但当改性共聚酯树脂与环氧化物固化物混合并随后在基材上加热时，这些端基的反应速度比传统的在最终混合过程中引入环氧化物催化剂的反应速度更快。用环氧化物固化化合物改变改性共聚聚酯树脂的固化参数，可使其在 300 °F 至 450 °F 的温度范围内具有更高的抗冲击强度和更好的流平性能。

  A polyester which when made into an article such as films, containers, bottles and the like has a very high clarity, a low haze value, and a neutral hue. In the preparation of the resin, an antimony catalyst is utilized along with small amounts of a bluing agent such as a cobalt compound and a phosphate compound with the phosphate compound generally being slightly in excess of an equivalent amount of the cobalt compound. The polyester is made from dicarboxylic acids and preferably aromatic acids such as terephthalic acid reacted with polyhydric alcohols.
