| titleOfInvention | PREPARATION OF CHLORINATED POLYOLEFINS. |
| abstract | Method and apparatus for treating polyolefins with chlorine in an aqueous suspension. Said method consists in subjecting the suspension of polyolefins to a submerged jet of chlorine gas at a speed sufficient to atomize the chlorine, namely at least 18.3 m / s (approximately 60 feet per second). By this process, a very intimate mixture of chlorine and aqueous suspension is formed, in which the chlorine treatment is carried out more efficiently and at a lower chlorine pressure. Said method has the advantage in particular of making it possible to obtain a more uniformly substituted product. Figure 1 shows a means of introduction of the gas jet. An orifice (3) extends through and outward from the interior of the wall of the container (2). An internal buffer (4) provided with an internal passage (5) is disposed inside the orifice (3). The buffer (4) forms with the orifice (3) and with a gas distribution pipe (6) a gas-tight closure. One of the ends (5a) of the passage (5) widens and forms a continuation of the enlarged end (6a) of the gas distribution pipe (6). The other end of the passage (5) opens into the interior of the reactor (1). The outlet end (4b) of the buffer (4) extends obliquely a short distance into the interior of the reactor (1). The inlet end (4a) of the buffer (4) tapers outwards in order to conform to the enlarged end (6a) of the gas distribution pipe (6), thus forming a tight seal gas when the flanges (7, 8 and 9) of the tanpom (4), the orifice (3) and the pipe (6) are fixed to each other as seen in Figure 1. |
