    Liquid chlorinated paraffine was used as a softener for SBR. The paraffine was found to be the excellent softener which afford the vulcanizate of both high tensile strength at break and good heat resistance, when it was used with phenol-formaldehyde resin. Remarkable improvements in 300% modulus, tensile strength at break, and tear resistance of the sulfur vulcanizate were able to attain by compounding the paraffine with both stannous chloride and liquid nitrile rubber.

    The present study was designed to improve the physical properties of the vulcanizate of butyl rubber/ SBR blend by using alkylated phenol-formaldehyde resin/stannous chloride with chlorinated liquid paraffine as inherent ionic curing agents. The physical properties of the vulcanizate cured with the ionic curing agents were compared with those of the sulfur vulcanizate.
    Both processibility of the unvulcanized compound and physical properties of the resin cured vulcanizate were successfully improved by using less than 10 phr of the liquid chlorinated paraffine. Remarkably, the heat resistance, compression set, modulus, and tensile strength at break of the ionic vulcanizate of butyl rubber/SBR blend were found to be superior to those of the sulfur vulcanizate. The former, as compared with the vulcanizate of butyl rubber or SBR alone, was nearly equal or a little higher in the tensile strength at break.

    It is known that some reagents such as ammonium acetate and magnesium carbonate improve transparency of natural rubber and Butyl rubber, but few reports which regarded to organic transparent agents have been published.
    Thus, we attempted to develop some organic agents, and found that amine derivatives or thiourea derivatives improve transparency of natural rubber and synthetic rubbers such as SBR, NBR, polychloroprene, polybutadiene, Butyl rubber, and synthetic natural rubber.
    Approximatelies, activity of these agents are inversely proportional to their molecular weights. Additional experiments showed that white carbon such as Nipsil VN3 or Aerosil is necessary for this object.
