This invention relates to a reaction injection molding process for preparing a molded product by reaction of a mixture of (a) an organic polyisocyanate; (b) one or more compounds containing at least two isocyanate-reactive groups; (c) about 2 to about 20% by weight, based on the weight of the molded product, of rigid fibers having a diameter of from about 5 to about 10 micrometers and a length ranging from the diameter of the fiber up to about 2 millimeters, preferably in admixture with component (b); and, optionally, (d) an inert gas dissolved in at least one of components (a) or (b) in an amount sufficient to produce a molded product having a density of at least 0. 80 g/cm. sup. 3 ; and (e) up to 15% by weight, based upon the weight of the molded product, of a filler other than rigid fibers (c).

A process for incorporating sulfonic acid groups in the structure of an aliphatic, non-polar, water insoluble compound is disclosed. In the process the compound is first dissolved in an appropriate solvent and is then reacted in the presence of a catalyst and oxygen with an aqueous sulfite solution. The sulfonation renders the compound polar and water absorbent and, therefore, suitable in a variety of applications.

A soft, flexible foam characterized in having (i) a hardness, IFD 25% value, of at most 29 lbs/50 in. sup. 2, as determined in accordance with Test B. sub. 1 of ASTM D 3574 and (ii) a density of about 0. 9 to 3. pounds per cubic foot is disclosed. Accordingly, the foam is prepared by reacting an organic polyisocyanate with a polyol in the presence of a catalyst and water and a compound conforming to ##STR1## where A is selected from among H, COOH, NH. sub. 2, and OH, M is a counter ion, and where n, x and m are selected such that said compound has a number average molecular weight of about 500 to 20,000, a functionality of 0 to 10 and a sulfonate concentration of about 0. 1 to 30 percent by weight.
