Systems and methods are provided for determining the size of particles within a fluidized bed reactor for use with thermally decomposable silicon-containing gas. The pressure of gas adjacent a gas inlet and adjacent a gas outlet of the reactor are measured with pressure sensors. An algorithm is applied to at least one of the pressure measurements to determine the size of particles within the reactor. The determined size of the particles can be used to control the operation of the reactor.

A dosing system and method is provided for measuring defined volumes of particles for transport to the reactor.

Systems and methods for particle size determination and control in a fluidized bed reactor

A copolycarbonate-polyester, comprising units of formula wherein at least 60 percent of the total number of Rgroups are divalent aromatic organic radicals and the balance thereof are divalent aliphatic or alicyclic radicals; units of formula wherein T is a Cdivalent alkyl aromatic radical or a Cdivalent aromatic radical, and D is a divalent Caromatic radical; and units of the formula wherein Rand Rare each independently a halogen or a Calkyl group, Ris a methyl or phenyl group, each c is independently 0 to 4, and T is as described above.

The present invention relates to a polymer composition comprising a transparent polymer blend. The polymer blend comprises a first resin and a second resin. The first resin comprises polyarylate structural units of formula I, wherein Ris independently at each occurrence a C&#x2013;Calkyl group, or a halogen atom, and p is 0 to 3. The second resin is selected from the group consisting of polycarbonates, polyarylates and copolyestercarbonates. The first resin and the second resin are further characterized by a difference in polyarylate structural unit content, said difference being less than about 40 mole percent.
