1. An apparatus for carrying out a polymerisation reaction to produce a drag reducing polymer, said apparatus comprising a housing in which a distended receptacle is arranged, wherein said distended receptacle is arranged to receive reagents for reaction in the apparatus, wherein said housing comprises a first elongate tube in which said receptable is positioned, wherein said first elongate tube has an internal surface wherein at least 60% of the area of an external wall area of said receptacle contacts said internal surface; and
wherein said housing comprises a second elongate tube which is coaxial with said first tube and said first tube is positioned within the second tube, said first and second tubes being radially spaced apart so an annular gap is defined between the first and second tubes, wherein said annular gap defines a fluid passage for a coolant fluid.
