Following the previous paper1), some new active calcium carbonates were studied for reinforcement of styrene-butadiene rubber. These active calcium carbonates were prepared by means of several ways whereby carbon dioxide gas was introduced to calcium hydroxide solution in the presence of chemical reagent as activator.<br>These reagents used for this purpose can be classified into two groups. That is (1) organic compounds having group such as amine, mercaptan or hydroxide besides carboxylacid, for example, sodium glutaminate, hystidine, lysine, arginine, phenylalanine, p-aminobenzoic acid, lactic acid, p-hydroxybenzoic acid, gallic acid, thioglycolic acid, thiosalicilic acid, sulfanic acid, serine, tyrosine and cysteine, and (2) sodium sulfide and/or polysulfide, and calcium sulfide and/or polysulfide.<br>After two or three parts by weight (based on hundred parts of calcium oxide) of these reagents were reacted with calcium hydroxide solution, active calcium carbonate were obtained by introducing of carbon dioxide.<br>SBR vulcanizates loaded with these active fillers indicated good physical properties. As the results, tensile strength at break of some of them were three or five times as high as that of vulcanizate loaded with conv- entional calcium carbonate.<br>It was shown that the excellent activators were sodium glutaminate, lysine, gallic acid, sodium sulfide and/or polyscelfide, and calcium sulfide and/or polysulfide.<br>By means of electromicroscorpe, diameters of active calcium carbonate particle activated with sodium glutaminate were found to be about 0.03μ and the dispersion of the above filler as well as that activated with sodium sulfide and/or polysulfide were both fairly good.<br>1) J.
