Abstract: A composition for use in the treatment of glass fibers and glass fibers treated with same for use as reinforcement for elastomeric materials in the manufacture of glass fiber reinforced elastomeric products comprising a blend of a resorcinol-aldehyde resin and an elastomer and a coupling system comprising an amino-substituted organo silicon compound and an organo silicon compound containing at least one beta-haloalkoxy group.

Abstract: Glass fibers coated with a blend of a resorcinol-aldehyde resin, an elastomer and a combination of organo silicon compounds formed of (1) an amino-substituted organo silane and/or its hydrolysis product and an organo silicon compound containing at least one beta-haloalkoxy group formed by reaction of a halosilane, a monoepoxide and a diepoxide.

Abstract: A composition for use in the treatment of glass fibers to promote a strong bonding relationship between glass fibers and plastics and elastomeric materials comprising a silanized butadiene polymer which has been reacted with a halosilane and the product reacted with an epoxide to replace the halogen groups of the silane with beta-haloalkoxy groups.

Abstract: Organo silicon compounds prepared by reaction of a dialkyl hydrazine of the formula ##EQU1## wherein R.sub.1 and R.sub.2 are each alkyl with an epoxy silane such as an epoxy silane of the formula ##EQU2## or an epoxy silane of the formula ##SPC1##Where y is an integer and R.sub.5 is alkyl. The organo silicon compounds described can be employed in the treatment of glass fibers to improve the bonding relationship between glass fibers and resins or elastomeric materials.

Abstract: Organo silicon compounds having the formula ##EQU1## wherein R.sub.1 and R.sub.2 are alkyl, R.sub.5 is a hydrocarbon group or an unsaturated ester group, R.sub.6 and R.sub.7 are alkoxy, R.sub.5 or hydrogen, and R.sub.8 is hydrogen or an organic group such as hydrogen, alkyl or a group of the formula--CH.sub.2 --O--R.sub.4 --where R.sub.4 is aryl, alkyl, alkenyl or a group of the formula ##EQU2## where R' is hydrogen or methyl. The compounds of this invention are prepared by reaction of a dialkyl hydrazine with an epoxide in the presence of an organo silicon compound and are used as coupling agents in the treatment of glass fibers. Also disclosed are glass fibers coated with aminimide compounds containing aluminum, gallium, phosphorus, arsenic, antimony, boron, germanium or tin.

Abstract: A method for producing a phenolic molding is disclosed. The method includes the steps of mixing phenol, formaldehyde and a hydraulic cement, forming the resulting composition to a predetermined shape and maintaining the composition in the predetermined shape until an insoluble, infusible article is formed by condensation. At least 10 percent of the hydraulic cement must be Portland cement. The mole ratio of formaldehyde to phenol must be at least 1:1, and the amount of hydraulic cement must be sufficient for reaction with from 1 to 9 times the sum of the water of condensation of the phenol with the formaldehyde and the water charged to the mix. The use of reinforcing glass fibers in producing phenolic moldings is also disclosed, as well as the use of urea and resorcinol in addition to the phenol, formaldehyde and hydraulic cement.

Abstract: A composition for use in the treatment of glass fibers for use as reinforcement for plastics and elastomeric materials and glass fibers treated therewith in which the composition is formulated to include the reaction product of a silicon halide such as silicon tetrachloride with an aliphatic epoxide containing at least fourteen carbon atoms.
