Increasing productivity of suspension polymerization of vinyl chloridemonomer using cocktail initiators and acid catalyst

The PVC reactor's cooling capacity matches the maximum polymerization rate for a specific batch.In VCM polymerization, the reaction rate rises, peaks, and then declines. As the average rate is lower,the cooling capacity is often underutilized. Adjusting decomposition rate of initiators by addingmethanesulfunic acid , can improve and optimize productivity by efficiently using the coolingcapacity. Choosing an optimal mixture of mild and slow initiators with proper value of acidic catalystcan significantly reduce processing time for a specific polymer specification, compared to using onlymixture of initiators. Maximum reduction in reaction time relative to the cocktail case with the sameK value and final conversion was ۳۳۳ for cocktail/acidic catalyst recipe.
