ABSTRACT:
An active hydrogen compound-alkylene glycol composition comprises components (A) a relatively high equivalent weight material having an average of at least about 1.8 active hydrogen containing groups per molecule and a weight from about 500 to about 5000 per active hydrogen containing group; (B) an alkylene glycol; and (C) a catalytic amount of at least one tin mercaptide; said composition containing at least one compound having at least one N--H containing group. Such compositions are useful in producing polyurethanes. The compositions can generally be stored without substantial loss of activity.
