  The invention pertains to a process to polymerize one or more monomers wherein at least one initiator and optionally at least one surfactant are added to a polymerization mixture when the pressure in the polymerization reactor is dropping. This process allows a shorter polymerization time due to a higher pressure drop rate at the end of the polymerization reaction. Moreover, the cooling capacity of the polymerization reactor is used more efficiently.

  本发明涉及一种聚合一种或多种单体的工艺，其中，当聚合反应器中的压力下降时，将至少一种引发剂和可选的至少一种表面活性剂加入聚合混合物中。由于聚合反应结束时的压力下降率较高，这种工艺可以缩短聚合时间。此外，聚合反应器的冷却能力也得到了更有效的利用。
