Polyurethanes having a two phase morphology and characterized by high impact strength and, optionally, high modulus are obtained by reaction of 4,4'-methylenebis(phenyl isocyanate) and modified forms thereof with an aliphatic glycol extender and a blend of at least two polyoxypropylene-polyoxyethylene polyols both of which have average functionalities in the range of 2 to 4, one of which has a molecular weight in the range of about 3000 to 10,000 and contains at least 23 percent by weight of ethylene oxide residues and the other has a molecular weight in the range of about 750 to about 2000 and contains at least 45 percent by weight of ethylene oxide. The two or more such polyols are employed in proportions such that the aliphatic glycol extender is completely miscible with said polyols if blended together.

Flexible polyurethane foams are prepared from inert gas frothed mixtures of (1) a polyether polyol end-capped with at least 2 moles of ethylene oxide per OH group, (2) an isocyanate containing prepolymer and (3) a catalyst for urethane formation.

Air frothed polyurethane foams

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.

Process for making a cationic methacrylamide

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° C. or in a two step process by first admixing the components at less than 130° C. and then postcuring the product at greater than 150° 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.
