摘要
考察了引发剂用量、悬浮剂用量、搅拌速度与反应温度对苯乙烯悬浮聚合反应的影响。结果表明,在苯乙烯用量为16 mL、去离子水用量为130 mL、引发剂过氧化二苯甲酰(BPO)用量为0.3 g、悬浮剂0.3%的聚乙烯醇溶液用量为7～8 mL、搅拌速度为300 r.min-1、反应温度为85～90℃的最佳悬浮聚合条件下,可得到颗粒尺寸均匀适中、透明度良好的聚苯乙烯产品,产率高达98.60%左右。
The effects of initiator dosage, suspension agent dosage, stirring speed and reaction temperature on styrene suspension polymerization were investigated. The optimum conditions were obtained as follows：styrene amount 16 mL, deionized water amount 130 mL,initiator（benzoyl peroxide） dosage 0. 3 g, suspension agent （0.3% polyvinyl alcohol solution） dosage 7-8 mL, stirring speed 300 r · min-1 ,reaction temperature 85-90 ℃. Under above conditions,the polystyrene with appropriate particle size, good transparency and high yield of about 98.6% could be obtained.
