Abstract:
1. A continuous static polymerisation reactor unit for the production of liquid polymers in a predetermined viscosity range which comprises: a) a reactor comprising an elongate hollow reaction chamber having two ends, one end defining an inlet means adapted for the introduction of a reaction mixture into the reaction chamber, and the other end defining an outlet means; b) a supply means in communication with the inlet means for supplying liquid monomers, oligomers, or mixtures thereof to said inlet means; and c) means for introducing at least one viscosity controlling agent into the supply means to form a reaction mixture with the monomers, oligomers or mixtures thereof, wherein the temperature and flow rate values of the resulting polymer in the elongate hollow reaction chamber are maintained substantially constant; and d) a control means adapted to detect and correct any variation from a predetermined pressure drop value between the inlet means and the outlet means.
