ABSTRACT:
A flame retardant liquid rubber composition comprises a hydrogenated polyhydroxybutadiene polymer and castor oil, which are modified with an isocyanate having the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 respectively represent a lower alkyl group or hydrogen atom and n is an integer of 1 to 4, and alumina hydrate and magnesium hydroxide. The castor oil can be incorporated before adding said isocyanate or can be converted into an isocyanate prepolymer by reacting with said isocyanate before the addition.
