Aromatic polyalkyleneoxy polyamines which are the reaction products of an aminocarbonyl, a polyalkyleneoxy polyamine, and aromatic diamines are useful in reaction injection molding processes to enhance the physical properties of the products produced. In addition, the polyamines of this invention are also useful as compatiblilizing agents in RIM systems to compatibilize mixtures of high molecular weight and low molecular weight polyols.

Mixtures of high molecular weight polyols and low molecular weight polyols such as mixtures of glycerine initiated polyoxypropylene glycols and mono- and diethylene glycols are rendered resistant to phase separation upon storage by the addition thereto of from about 0. 2% to about 3. 0% by weight of colloidal silica or an onium modified clay such as Bentone 27.

Mixtures of high molecular weight polyols and low molecular weight polyols such as mixtures of glycerine initiated polyoxypropylene glycols and mono- and diethylene glycols are solubilized and therefore rendered resistant to phase separation upon storage by the addition thereto of an effective quantity of a derivative of butylene glycol or propylene glycol such as dibutylene glycol.

This invention is an active hydrogen-containing composition comprising (A) a relatively high equivalent weight liquid active hydrogen-containing material or mixture thereof having at least 50% of its active hydrogen containing groups in the form of primary and/or secondary amine groups; (B) a chain extender having an equivalent weight of about 31 to about 250 and about 2 active hydrogen-containing groups per molecule; and (C) from about 1 to about 30 parts, per 100 parts by weight of the composition, of an amide formed by the reaction of a C. sub. 2 -C. sub. 30 monocarboxylic acid with a relatively high equivalent weight amine-terminated polyether.

Polyurea polymers prepared from formulations including a polyisocyanate, a polyamine and a polyepoxide can have good heat stability and good physical properties in the substantial absence of uretidine diones and isocyanurates. The polymers can be prepared in one step of admixing and heating at greater than 150. degree. C. or in a two step process by first admixing the components at less than 130. degree. C. and then postcuring the product at greater than 150. degree. C. The polyurea polymer, after postcuring, can have substantially no residual epoxy or oxazolidinone groups. These polymers were particularly useful for applications which require the exposure of the polyurea polymers to both intermittent high temperatures and high humidity. The polyurea polymers of the present invention can withstand higher temperatures than conventional polyurea polymers without blistering.
