Abstract

DC60 (19/03/41) Disclosure is a polymerization process that consists of feeding monomers as raw materials, polymerization catalysts and possibly inert media. Into the reactor in the pressurized state, allowing part of the monomer, raw material and inert medium fed into the reactor to form a gas phase and the rest to form a liquid phase so that the entire gas cycle Containing Raw material monomer and / or inert medium And the liquid phase containing raw material monomer and / or inert medium. Exist in the reactor Where such liquid phase may contain polymers formed in solid form and to allow gas-liquid separation or gas-liquid-solid separation flow, there is a continuous gas phase in the direction. The flow taking place in the reactor And polymerization monomers of raw materials, while the liquid phase is passed by the gas phase where the ratio of flow rate, volume of liquid phase to Flow rate, volume of gas cycle at the outlet of the machine Reactors are 0.00001 to 100,000 according to the polymerization process. Polymerization can be performed with high efficiency. It is also capable of producing a wide range of polymers with almost no restrictions on properties such as viscosity and melting point. The revealing message is a polymerization process that consists of feeding monomers as raw materials. Polymerization catalysts and may contain inert media. Into the reactor In the state of pressure This allows part of the monomer, raw material and inert medium fed into the reactor. It is a gas phase cycle and the remainder forms a liquid phase so that the whole gas phase contains raw material monomer and / or inert medium. And the liquid cycle containing monomer Raw materials and / or inert media Exist in the reactor Where such liquid phase may contain polymers formed in solid form and to allow gas-liquid flow or gas-liquid-solid separation flow, there is a continuous gas phase in the direction. Flow taking place in the reactor And polymerization mono Raw materials while the liquid phase is carried by the gas phase where the ratio of the volumetric flow rate of Continuing fluid cycle Flow rate, volume of gas cycle at the outlet of the machine Reactors are 0.00001 to 100,000 according to polymerization process. Efficiency It is also capable of producing a wide range of polymers with almost no restrictions on properties such as viscosity and melting point.
