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