  • Thermoset molding compositions
    Patent number: 4673696
    Abstract: Disclosed is a storage stable blend of a long chain polyol and a short chain diol wherein the diol is present in an amount whereby the diol and polyol form an incompatible blend. The blend is rendered storage stable by the addition of a compatibilizing amount of an ethylenically unsaturated esterol. Alternatively, the compatibilizing agent comprises an adduct of the ethylenically unsaturated esterol and a polyol, e.g. glycol. The storage stable blends find utility in making rigid, tough RIM parts.

  • Process for the manufacture of carbon fibers and feedstock therefor
    Patent number: 4671864
    Abstract: Disclosed herein is an improved pitch for making readily stabilizable, substantially nonmesophasic carbon fibers. The pitch has a softening point of about 250.degree. C.(480.degree. F.) or above and is produced from an unoxidized thermal petroleum pitch by selectively reducing or eliminating a portion of the low molecular weight materials in a very short period of time so that the tendency to produce mesophase pitch is eliminated or reduced and so that the chemical integrity of the components of the higher molecular weight fractions is preserved as much as possible. Also disclosed is a method of producing carbon fibers therefrom and rovings or mats from such fibers.

  • Dry blending with fibers
    Patent number: 4669887
    Abstract: Disclosed is a method and apparatus for avoiding the clumping of fibers having diameters and lengths in certain ranges during dry blending of such fibers into a dry matrix material. The process comprises distributing fibers in a vaporous medium, and transporting fluidized fibers to a mixing zone containing a dry matrix material. Concurrently with stirring and blending of the dry matrix material with fluidized fibers, the fluidized fibers having been separated at least partially from a fluidized vapor are gradually introduced into the mixing zone. This process avoids the phenomena of "balling" that otherwise occurs with certain fibers.
