A process for making an aqueous emulsion of polyolefin employs a functionalized emulsification facilitating compound. The aqueous emulsion can be used to prepare a hybrid polyolefin-polyurethane dispersion useful, inter alia, as an adhesion-promoting coating for polymers such as the polyolefins.

Process for the preparation of a polyolefin emulsion and hybrid polyolefin-polyurethane dispersion derived therefrom

A process for making an aqueous emulsion of self-emulsifiable polyolefin employs a high molecular weight functionalized polyolefin and a hydrophilic polymer. The aqueous emulsion can be used to prepare a hybrid polyolefin-polyurethane dispersion useful, inter alia, as an adhesion-promoting coating for polymers such as the polyolefins.

A sizing composition which includes an anionic or cationic polyurethane dispersion, a polyolefin wax and a coupling agent.

Sizing composition

A polyurethane dispersion which is the reaction product of a prepolymer and a water or hydrazine chain extender. The prepolymer is the reaction product of a hydroxylated polyalkadiene, a bis(hydroxyalkyl) quaternary ammonium-group-containing diol and a polyisocyanate.

Cationic polyurethane dispersion and composition containing same

The preparation and use of quarternized bis hydroxy alkyl amines by the reaction of a tertiary amine and an alkylene oxide in a strong acid system are disclosed. Cationic polyurethane compositions containing pendent hydroxy alkyl groups and methods for their preparation are also disclosed.

Cationic polyurethane compositions, quaternary ammonium salts and methods for their preparation

Polyester polyols which contain at least one dihydrazide linkage --C(.dbd.O)--NHNH--C(.dbd.O)-- reduce the incidence of scorching when used as a reactant in the manufacture of polyurethane foam. Also disclosed are compounds of structures (2) and (3):

Scorch resistant additives for polyurethane foams

Disclosed are aqueous polyurethane dispersions prepared from polyester polyols having 0.95 to 1.5 equivalents of carboxylic functionality thereon per equivalent of polyol, the dispersions also containing a nonionic surfactant component wherein the ratio by weight of said carboxylic functionality to said nonionic surfactant component is 1:2.5 to 1:0.5. The dispersions are particularly adapted to the formation of thin wall articles exhibiting greatly improved properties.

Polyurethane dispersions useful for preparing thin wall articles

Disclosed are aqueous dispersions of polyurethane polymers from which films can be formed which have enhanced hydrophilicity. The enhanced hydrophilicity is provided by hydrophilic moieties chemically incorporated in the polymer network.
