Filled liquid, polyhydroxyl-containing polymers such as polyether and polyester polyols can be increased in viscosity by incorporating therein a tertiary alkanol monoamine.

Tertiary alkanolamines to increase viscosity of filled liquid polymers

Curable compositions and a process for the preparation of a low viscosity, filled liquid polymer having active hydrogen-containing groups are disclosed. An organic zirconium compound lowers the viscosity of a combination of a liquid polymer and an inorganic filler.

Organic zirconium compounds to reduce viscosity of filled liquid polymers

The subject matter of this invention pertains to polyurethane sealant compositions which are flexible, strong, and resistant to shrinkage. The sealants are prepared by reacting a mixture of polyether polyol and inorganic filler with a polyisocyanate. The polyurethane sealants are useful for making castings, for patching, and as heat barriers.

Polyurethane sealant compositions

The subject matter of this invention relates to the preparation of polyurethanes. It is particularly concerned with the use of certain organo-zirconium and organo-mercury compounds as co-catalysts in the preparation of polyurethanes.

Zirconium and mercury compounds as co-catalysts for the preparation of

By using a polyether polyol grafted with a suitable proportion of a suitable vinyl-type monomer with the use of a free-radical catalyst, it is possible to obtain filled or unfilled castings of thermosetting polyurethane which has excellent physical properties as well as good processing characteristics.

Preparation of polyurethane from a blend of polyether polyols and a

The reaction of an organic polyisocyanate with an organic compound containing at least 2 active hydrogen containing groups is catalyzed with a synergistic co-catalyst combination of at least one organo-mercuric catalyst and at least one zinc salt of an alkylcarboxylic acid having about 2 to about 22 carbon atoms. Useful solid (non-cellular) and foamed polyurethane products are obtained which are produced at a faster curing rate than with use of either co-catalyst alone.

Synergistic polyurethane co-catalysts which are a combination of an

The addition of small amounts of organic titanium compounds to polyol compounds reduces the viscosity of said compounds.
