Abstract
Метод за суспензионна хомо-или съполимеризация на винилови мономери, по-специално винилхлорид с използване на стабилизираща и/или порообразуваща добавка по време на полимеризационния процес и в даден случай с добавка на диспергиращо средство, хараткеризиращ се с това, че като стабилизираща и/или порообразуваща добавка се използват частично хидролизирани поливинилацетати със степен на хидро лизиране от 30 до 92% мол. В количество от 0,05 до 0,3% тегл., За предпочитане от 0,08 до 0,15% тегл. По отношение теглото на вложените мономери. Патентните претенции са формулирани в 2 точкиA method for suspension homo- or copolymerization of vinyl monomers, in particular vinyl chloride using a stabilizing and/or pore-forming additive during the polymerization process and in a given case with the addition of a dispersing agent, characterized in that as stabilizing and/or partially hydrolyzed polyvinyl acetates with a degree of hydrolysis of 30 to 92% mol are used as a pore-forming additive. In an amount of from 0.05 to 0.3% by weight, preferably from 0.08 to 0.15% by weight. In relation to the weight of the monomers inserted. The patent claims are formulated in 2 points
