    Abstract: This invention relates to o-tolylenediamine-based polyether polyols having an OH number of about 400 to 630, in which about 5 to 20% of the isocyanate-reactive groups of the polyether polyols are secondary amino groups and which contain less than about 0.2% by weight free o-tolylenediamine. The polyether polyols of the invention are formed by sequential reaction of o-tolylenediamine first with about 2 to 5 mol of ethylene oxide and then with about 1 to 5 mol of propylene oxide per mol of o-tolylenediamine. This invention also relates to the process for the production of polyether polyols using said sequential reaction at a temperature of about 90.degree. to 125.degree. C. and in the presence of an amine catalyst. This invention further relates to a method for the production of polyisocyanate-based plastics, preferably polyurethane foams, comprising reacting organic polyisocyanates with polyether polyols of the invention and compounds containing at least two isocyanate-reactive hydrogen atoms and having a molecular weight range of about 200 to 1,500, and optionally also with chain-extending agents or crosslinking agents and auxiliaries or additives.
