Description

Изобретение относитс  к области получени  поливинилхлорида.The invention relates to the field of polyvinyl chloride.

Известен способ получени  поливинилхлорида (ПВХ) путем эмульсионной полимеризации внпилхлорида в присутствии персульфата аммони  в качестве инициатора. Этот процесс протекает с нарастающей скоростью по мере образовани  твердой полимерной фазы. Интенсивность тепловыделени , пропорционального скорости полимеризации, особенно резко возрастает в конце процесса, и при высоких степен х конверсии процесс становитс  неуправл емым.A known method of producing polyvinyl chloride (PVC) by emulsion polymerization of vinyl chloride in the presence of ammonium persulfate as an initiator. This process proceeds at an increasing rate as the solid polymer phase forms. The intensity of heat generation, proportional to the rate of polymerization, increases especially sharply at the end of the process, and at high degrees of conversion, the process becomes uncontrollable.

Предлагаемый способ отличаетс  тем, что в качестве инициатора примен ют бис-1-(1-алкил-4 ,5 - диоксолан - 3 - ОП) - перекись общей формулыThe proposed method is characterized in that the initiator used is bis-1- (1-alkyl-4, 5-dioxolane-3-OD) -peroxide of the general formula

Натной температуре как в кристаллическом состо нии, так и в виде нейтральных растворов в органических растворител х. Например, в бензоле при 80°С перекись не разлагаетс  в течение 8 час. Добавление к растворам воды или вендеств основного характера вызывает распад перекиси, причем скорость распада ее зависит от силы основани Natal temperature both in crystalline state and in the form of neutral solutions in organic solvents. For example, in benzene at 80 ° C, peroxide does not decompose within 8 hours. Addition of basic water to water or vein solutions causes the decomposition of peroxide, and its decomposition rate depends on the base
