Title: Glass fibers coated with silicon containing aminimide compounds

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.
