Abstract
Polyhydroxybutadiene compounds are storage stabilized against reactivity changes by incorporating therein an effective amount of a di or triphenyl phosphine compound of the formula ##STR1## wherein each x is hydrogen, a halogen or an alkyl or alkoxy group having from 1 to 10 carbon atoms and y is an alkyl group having from 1 to 10 carbon atoms or an aryl group which may be substituted with a halogen or an alkyl or alkoxy group having from 1 to 10 carbon atoms.
