Abstract
Degradable polymers, including polyurethane and polyurethane-urea compositions, that can be used in aqueous, non-aqueous and dry hot environments as degradable polymers in oil, gas and other applications. Such polymers may be formed from polyurethane-forming compositions, including: (a) an isocyanate component; (b) one or more polyols; (c) a degrading-agent, and (d) optionally, one or more additives. A stoichiometric equivalent of the isocyanate (a) to the polyol (b) may be from about 80 to about 120%.
