Definitions

  • This invention relates to oil-free oxidatively curable polyesters and coating compositions containing the polyesters. More specifically, the invention relates to oxidatively curable oil-free polyesters and carboxyl functional oligomeric adducts, which have been modified with 3,4-epoxy-l -butene.
  • alkyd resins are the most common technology for ambient-cure coating applications.
  • An alkyd resin is a polyester incorporating vegetable oils or fatty acids.
  • the oils and acids contain unsaturated fatty acids such as oleic, linoleic, and linolenic acids. These unsaturated moieties exhibit labile hydrogen atoms which are capable of being abstracted and in turn initiate oxidation reactions. The oxidation reactions lead to crosslinking of the polyester molecules thus providing coatings with desired properties.
  • the alkyd resins utilized in these coating applications are usually highly-colored as a result of processing from lower grade colored oils or fatty acids.
  • a higher grade oil containing more desirable unsaturated fatty acids such as linoleic acid and linolenic acid, can be costly.
  • An alternative to the oil based alkyd technology is therefore desired.
  • Rokicki et al, in J. Appl. Polym. Sci. v.70, 2031 (1998) report that high hardness of coatings cured in air using photoinitiators can be achieved for an unsaturated polyester resin with polyfunctional allyl ether monomers incorporated into polyester molecules as the end groups or as the pendant geminal groups.
