Vinyl chloride polymerization in reactor coated with build-up suppressant product

摘要: Polymerization of vinyl chloride in aqueous suspension using a polymerization reactor having adherently deposited on internal surfaces thereof build-up suppressant coating comprising product activity formable by (and preferably formed by) the condensation an effective 1-naphthol (preferably itself) and formaldehyde. The is effected base-catalyzed reaction; it may also (less preferably) be acid-catalyzed reaction. itself process for its production are claimed.
