Abstract
The results of suspension polymerization of styrene were studied by changing the dosage of initiator, stirring speed, size of stirring paddle, content of dispersant and reaction temperature. The results showed that when using 500 ml four flasks, styrene 40 ml and polyvinyl alcohol solution (3 g polyvinyl alcohol dissolved in 1000 ml deionized water) 200 ml, initiator 0.5 g, stirring speed 300-450 r/min, temperature range 86-95°C, using the stepped heating method and using the impeller with a spreading blade diameter of 43 mm can ensure the success of the experiment, and the yield is relatively high.
