Vinyl halide polymerization process, reactor therefor and coating product for use in process and with reactor |
摘要 |
Build-up during vinyl halide, particularly vinyl chloride, polymerization is prevented by employing a polymerization process using a reactor having an adherent internal coating of a coating product derived from the admixture of at least polyethyleneimine; one or more of hydroquinone, p-benzoquinone, catechol and o-benzoquinone; and at least one o-aldehyde-substituted phenol, particularly salicylaldehyde. The preferred system is prepared from polyethyleneimine, hydroquinone and salicylaldehyde.
