Primary Suspension Agent for Polyvinyl Chloride Polymerization

Dissolution Method

Slowly charge GOHSENOL™ into room temperature water under agitation. Begin to raise the temperature to 70-75 degree C. After having fully dispersed GOHSENOL™, keep at this temperature for 30-60 under continued agitation until it has completely dissolved. Pay full attention to the temperature as dissolving time is significantly increased above 80 degree C. Sometimes turbidity due to the Clouding point is observed at 70-75 degree C. But this turbidity disappears after it has cooled. Be careful to avoid any rapid temperature increase, as this often causes severe foaming.
