ABSTRACT:
An organocyclosiloxane is disclosed which has both silicon-bonded alkoxy groups and organofunctional groups within each molecule. This cyclic siloxane finds utility as a coupling agent and has the general formula ##STR1## wherein R.sup.1 is independently selected from the group consisting of a monovalent hydrocarbon group having 1 to 8 carbon atoms and a monovalent halogen-substituted hydrocarbon group having 1 to 8 carbon atoms, R.sup.2 is selected from the group consisting of an alkoxy group and an alkoxysilylalkyl group, R.sup.3 is an organofunctional group selected from the group consisting of glycidoxyalkyl groups, methacryloxyalkyl groups, N-(trialkylsilyl)aminoalkyl groups, (hydroxyphenyl)alkyl groups, and haloalkyl groups and n and m each represent an integer having a value of 1 to 6 with the proviso that n+m is an integer with a value of 3 to 8.
