Abstract: A polymer is formed by capping a copolymer-graft-polylactone with an alcohol, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The polymer can be mixed with an organic solvent and pigment powder to form a dispersion. The dispersion can be mixed with a binder to form a paint.

Abstract: A carrier gas recycling system is designed according to the procedures in which a carrier gas passes through a reactor, such as a fluidized bed reactor, so as to purify and recycle gas generated in the reaction to substitute for the carrier gas externally applied to the reactor. The carrier gas recycling system includes an oil-water separation chamber to separate and purify carrier gas, and a liquid-sealed constant pressure tank to reduce carrier gas pressure fluctuation and expel extra reaction-generated gas. The carrier gas recycling system also controls the carrier gas flow by controlling the rotating speed of a blower for transferring the carrier gas, and utilizes a heat supply device used in the reaction process to preheat the carrier gas.
