  • Patent number: 4965298
    Abstract: A process for preparing aqueous polymer solutions wherein a section of a fluid conduit through which a stream of liquid polymer product flows contains spaced static mixers. Heated water from a heat exchanger surrounding the section of conduit containing the mixers is introduced to a reactor to function as reaction water. The static mixers are spaced apart enough to enable the heat exchanger to sufficiently cool the liquid polymer product. The mixers function to mix other liquid agents with the liquid polymer product and to mix together warmer and cooler quantities of liquids encountered in the conduit.
