  • Patent number: 4943610
    Abstract: A non-shrinking, strain-free, dimensionally-stable modified epoxy resin is disclosed for use in the fabrication of composite, structural laminates. The uniqueness of product preparation is that the optimum amount of the lactone compound can be copolymerized with the epoxy resin since equimolar amounts of each monomer do not necessarily need to be copolymerized to achieve the optimum shrink resistance. By varying the ratio of shrink-resistant monomer and epoxy in a resin blend, a means is available for controlling the shrinkage, and, in this manner, it would be possible to produce a laminate with a matrix so tailored so that reinforcing fibers would not undergo breakage, or pull out of the matrix on being stressed. The modified epoxy resin is the reaction product produced from reacting a compound selected from 6-hexanolactone and 5-norbornene-2,2-dimethanol with the diglycidyl ether of bisphenol A and cured with the curing agent hexahydrophthalic acid.

According to this process, a polyester of excellent physical property can be obtained at a good production efficiency.

  • Patent number: 4485220
    Abstract: A modified unsaturated polyester (polyesteramide) is the reaction product of a diacid or anhydride (such as maleic anhydride), a polyahl (such as an aliphatic glycol), and an effective amount of a poly[(alkionylimino)alkylene] (such as poly[(propionylimino)ethylene], otherwise known as poly(2-ethyl-2-oxazoline)) wherein at least one of the diacid or anhydride, and the polyahl, have addition polymerizable unsaturation. The modified polyesters of the invention have improved physical properties compared to similar polyesters prepared without the poly[(alkionylimino)alkylene].
