Abstract
A method and composition for decreasing the viscosity of mercaptan terminated polymers. The method involves adding thiol terminated trithio-orthoformate polycondensates to the mercaptan terminated polymer to achieve desired decreases in viscosities without adversely affecting other physical properties. The polycondensates have the formula
