| titleOfInvention | Vulcanizable compositions |
| abstract | A vulcanizable composition comprises (1) the condensate of a saturated monoepoxide with a minor proportion of a monoethylenically unsaturated monoepoxide and (2) 5 to 45 mls. per 100 g. of the condensate, of a clay type filler, being a finely divided aluminium silicate or magnesium silicate in which it is preferred that at least 90% of the particles have a diameter less than 5 microns. The saturated epoxides generally have the formula <FORM:1110803/C3/1> in which R is a hydrogen atom or a saturated and unsubstituted hydrocarbon or hydrocarbonoxy group, e.g. ethylene, propylene, styrene oxides and phenyl glycidyl ether. The unsaturated epoxide preferably has the formula <FORM:1110803/C3/2> in which one of the groups Q1 and Q represents a hydrogen, whilst the other represents a monoethylenically unsaturated hydrocarbon group, or in which Q and Q1 represent hydrocarbon groups which may be linked together to form a cyclo-aliphatic group, one only of said hydrocarbon groups containing a monoethylenically unsaturated group. The hydrocarbon groups may contain ether or ester groups. Suitable unsaturated epoxides are butadiene monoxide, allyl glycidyl ether, vinyl cyclohexene monoxide, glycidyl acrylate and 2-methyl-5,6-epoxyhexene-1. In the examples a copolymer of propylene oxide and allyl glycidyl ether is prepared using an Al(C2H5)3/Zn(C2H5)2 mixture as catalyst and a hydrocarbon solvent. The copolymer is then compounded with, in Example 1, (i) an aluminium silicate filler, (ii) kaolin clay, (iii) carbon black (for comparison), and in Example 2, (i) aluminium silicate filler, (ii) and (iii) kaolin, (iv) talc (hydrated magnesium silicate), and (v) precipitated silica and with carbon black (for comparison). Sulphur and conventional vulcanizing agents are added and the mixtures vulcanized. |
