The flammability of acrylonitrile-butadiene-sytrene resin is significantly decreased by adding thereto a combination of a brominated aromatic ether and iron or chromium naphthenate.The brominated aromatic ethers which may be used are illustrated by the generalized structure: ##STR1##
A method and composition are disclosed wherein guayule rubber is fractionated into desirable weight average molecular weight fractions by a desired solvent system. Oftentime, a plurality of fractionating steps is utilized wherein the desirable molecular weight rubber fraction is prec
A process and urethane composition for making urethane prepolymers from a polyisocyanate and blends of two or more urethane intermediates. The prepolymers so produced when cured have improved physical properties such as high low strain modulus and tensile strength relative to cured p
Process for the production of vulcanizates of diolefin rubbers by irradiation of compositions containing such rubbers utilizing polyhydrosulfides such as 1,10-dimercaptodecane as direct promoters. Indirect promoters may also be used to lower the total dose requirements.
