Abstract
Rubbery copolymers of conjugated dienes, e.g. 1,3-butadiene, isoprene, 2-cyanobutadiene-1,3, pentadiene, piperylene, dimethylbutadiene and 2-methyl-pentadiene-1,3, and monomers of the formula CH2=C(R)-X where R is hydrogen, methyl, ethyl, propyl, or chlorine, X is -CN, -COONH2, -COR1 or -COOR1 and R1 is an alkyl group containing up to five carbon atoms, e.g. acrylonitrile, are stabilized by addition of 0.1 to 10 per cent of the alkylated cresylic acids described in Specification 678,927. The stabilizers may be added to the copolymer latex as an emulsion in sodium oleate solution or compounded on the mill with, for example, coumarone resin, magnesia, zinc oxide, clay, carbon black, titanium dioxide, stearic acid, sulphur and an accelerator and cured.ALSO:A tert-octylated cresylic acid is made by cooling to 5 DEG C. a mixture of a cresylic acid from petroleum (boiling range 92 DEG to 121 DEG C. at 10 mm.) and diisobutylene, adding concentrated sulphuric acid and stirring. After washing and drying over anhydrous sodium sulphate the mixture was fractionally distilled. The product (n27D=1.5070) was taken between 122 DEG and 166 DEG C. at 10 mm. It is used to stabilize synthetic rubbers (see Group IV (a)).
