ABSTRACT:
Inclusion of an effective amount of substantially anhydrous acetic acid in a zinc oxide cured liquid polysulfide polymer based composition results in a cured composition which is suitable for extrusion under heat and pressure and which on cooling reverts to a rubbery solid with essentially unchanged physical properties. The compositions are useful for the manufacture of sealants and extrudible goods such as hoses.
