Abstract: - Pptd. SiO2 (I) has a CTAB surface area (to ASTM D 3765-92) of 200-400 m /g, a DBP no. (to ASTM D 2414) between 230 and 380 ml/100 g as powder and 180-250 g/100 g as granulate; a silanol gp. density (V2 consumption of NaOH) of 20-30 ml; and a typical macropore size distribution for each surface area, determined by HG porosimetry (DIN 66133) for certain pore size intervals (incremental plot). For CTAB surface areas of (A) 200-250, (B) 250-3300, (C) 300-400 m /g, the Hg consumption is (A) 0.27-0.49, (B) 0.35-0.50, (C) 0.32-0.42 ml/g for 10-20 nm pores; (A) 0.22-0.32, (B) 0.15-0.30, (C) 0.17-0.22 ml/g for 20-30 nm pores; (A) 0.15-0.21, (B) 0.12-0.17, (C) 0.12-0.15 ml/g for 30-40 nm pores; (A) 0.11-0.16, (B) 0.09-0.12, (C) 0.08-0.11 ml/g for 40-50 nm pores; and (A) 0.08-0.12, (B) 0.06-0.10, (C) 0.06-0.09 ml/g for 50-60 nm pores. Also claimed are vulcanisable rubber blends contg. 5-100, esp. 15-60 phr (I); and rubber blends and/or vulcanisates contg. opt. silane-modified (I).
