IPC: C08F2/00
Filed: 1981-02-04
Abstract: PURPOSE: To obtain the titled polymer stably and continuously with prevented deposition of fine powder on the wall surface and clogging of a piping, by discharging the unreacted gas stream containing a fine powdery polymer from a vapor-phase polymerizing zone, leading the gas stream to a cyclone, collecting the fine powdery polymer, and circulating the fine powdery polymer through the polymerizing zone.  
     CONSTITUTION: In polymerizing an olefin in the vapor phase, a catalytic suspension prepared by preliminarily polymerizing a small amount of the olefin in the presence of a transition metallic compound catalytic component and an organometallic compound catalytic component in a separate vessel is fed from a pipe 1 through a heater 2 to gasify a liquid medium. The resultant suspension is then fed to a polymerizer 3 in which a fluidized bed 4 is formed on a perforated plate 6. The polymerization of the suspension is carried out while fluidizing the bed 4. An unreacted gas stream containing the resultant fine powdery polymer after passing through the fluidized bed 4 is then led from a pipe 7 to a cyclone 8 to collect the fine powdery polymer, which is then removed by the sucking with a sucking force from the bottom of the cyclone 8 and circulated through a vapor-phase polymerizing zone in the polymerizer 3 and polymerized.

Filed: 1993-02-01
Abstract: PURPOSE:To realize the polarized light sepn. element which can be produced by a simple production process without requiring mask alignment and has high reliability with good productivity and has good optical quenching ratio. CONSTITUTION:Proton exchange regions of depth dp are produced periodically on the surface of a lithium niobate substrate 20 of an x plane. The lithium niobate substrate 20 is formed by having about 62 deg. angle of the z axis with a desired polarized light sepn. direction 1. The refractive indices of the lithium niobate substrate 20 and the proton exchange regions are equal in this direction and, therefore, the polarized light in this direction passes the proton exchange regions 21 as it is without being affected by these regions. The depth of the proton exchange regions 21 is set at 3.9mum so as to constitute 0-pi phase gratings with the polarized light of the direction (polarized light sepn. direction 2) orthogonal with the polarized light sepn. direction 1. Therefore, all of the polarized light rays are diffracted and introduced outside the optical axis. The polarized light sepn. of the polarized light sepn. directions 1 and 2 is realized as mentioned above.
