Abstract: There is disclosed a novel organopolysiloxane-grafted polybenzobisoxazole and a method for preparing the functional organopolysiloxane-grafted polybenzobisoxazoles using a phthaloyl halide-functional organopolysiloxane.

Abstract: Novel 1-aza-3-oxa-4-silacyclohex-1-ene compounds, and tautomers thereof, having utility as chemical modifiers or cross linkers for hydroxy-containing organic or inorganic substances are disclosed, said compounds being represented by the general formula (I) ##STR1## wherein R.sup.1 and R.sup.2 each independently denotes a monovalent organic group having 1 to 6 carbon atoms selected from the group consisting of saturated hydrocarbon groups and unsaturated hydrocarbon groups, R.sup.3 deontes an organic group having 1 to 30 carbon atoms selected from the group consisting of saturated hydrocarbon groups and unsaturated hydrocarbon groups, said R.sup.3 groups optionally containing a heteroatom selected from the group consisting of oxygen, nitrogen, sulfur, silicon, fluorine, chlorine, bromine and iodine, Me denotes a methyl radical and n is an integer having a value of 1 to 4.

Abstract: An odor-resistant film-forming composition capable of preventing the migration and lingering of odors onto substrates, which contains a first type of silicon compound with an amino group and a plurality of hydrolyzable groups in the molecule and a second type of silicon compound without an amino group but with a plurality of hydrolyzable groups in the molecule, wherein at least one of the first type of silicon compound and second type of silicon compound includes a silicon compound which has 3 or more hydrolyzable groups in the molecule.

Abstract: The shortcomings inherent in prior art coupling fluids are eliminated by combining 1) a polyorganosiloxane fluid as the base oil with 2) sulfur or certain sulfur compounds and 3) at least one cyclic organosiloxane. These three ingredients form a suitable coupling fluid for use in viscous coupling systems.
