Continuous polymerization reactor

A process for the continuous polymerization of monomer, the process comprising:

• (a) adding monomer and catalyst to an annulus within an annular reactor to form a polymerization medium within the annulus, where the annulus includes the space between an outer casing wall and an inner tubular wall, wherein the inner tubular wall rotates around its longitudinal axis, and means for creating radial turbulence within the polymerization medium extend from the inner tubular wall into the annulus;
• (b) allowing the polymerization medium a sufficient residence time within the annulus to provide a polymer product;
• (c) removing the polymer product from the annulus.

A process for the continuous polymerization of monomer, the process comprising:

• (a) adding monomer and catalyst to an annulus within an annular reactor to form a polymerization medium within the annulus, said annular reactor having an outer casing wall and a shaft coaxial with said outer casing wall, wherein the annulus includes the space between the outer casing wall and an inner tubular wall provided by the shaft, wherein the shaft is sealed so as to prevent the polymerization medium from entering into the shaft, and wherein the inner tubular wall includes protrusions extending from the inner tubular wall and terminating within the annulus;
• (b) allowing the polymerization medium a sufficient residence time within the annulus to provide a polymer product;
• (c) removing the polymer product from the annulus.
