| description | Aluminum (oxide-)hydroxides useful as reinforcing filler for rubber. Aluminous reinforcing fillers for diene rubber compositions to be used in the manufacture of tyres, consisting of an aluminum (oxide-)hydroxide corresponding, including impurities and water of hydration, the formula (I) Al(OH) aO b (I) in which 0 a = 3 and b = (3-a)/2, and which has a specific BET surface of 30-400 (preferably 50-350) m 2>/g, an average particle size by weight of 20-400 (preferably 30-200) nm, and a rate of deagglomeration (alpha ) measured by the ultrasound deagglomeration test at 100 % power of a 600 watt ultrasound probe of greater than 5 X 10 -> 3> mu m -> 1>/s, preferably greater than 6 X 10 -> 3> mu m -> 1>/s. Independent claims are included covering: (a) a process for preparing the aluminous fillers (I); (b) sulfur-vulcanisable rubber compositions containing a white reinforcing filler which includes the aluminous filler (I) and a coupling agent; (c) a device (II) for measuring the rate of deagglomeration of a filler using ultrasonics; and (d) a method of measuring the rate of deagglomeration using the above device. |
