COMPOSITION FOR LINING THE WALLS OF REACTORS AND CONNECTED APPARATUS USED FOR POLYMERISING VINYL COMPOUNDS WHICH PREVENTS OR REDUCES DEPOSITS AND INCRUSTATIONS ON SAID APPARATUS, AND THE METHOD FOR ITS USE

摘要

A composition for lining the walls of reactors and other connected apparatus in contact with reactant mixtures and reaction products durinq the polymerisation of vinyl compounds, which reduces or prevents polymer deposits or incrustations on the said walls, constituted by the product of the prolonged reaction at C8 between a polyvinyl alcohol of medium degree of hydrolysis prepared by the controlled alkaline alcoholysis of an ester of a wide molecular weight distribution polyvinyl alcohol and a polycarboxylic oxyacid, in a weight ratio of between 35:10 and 40:10, which is applicable by known means, preferably by spraying.
