| titleOfInvention | Phenothiazine dimers and oligomers, process for preparing and use in reactor scale prevention |
| abstract | A composition having the formula (I), wherein n has an average value of one to about five, is disclosed for nuse in nreducing or eliminating the formation of reactor scale during the polymerization of vinyl chloride and ncomonomers. The ncomposition is prepared by reacting phenothiazine with formaldehyde in the presence of a liquid diluent that is a nsolvent nfor the phenothiazine, but a non-solvent for the dimer of phenothiazine and formaldehyde. The process of the ninvention is npreferably conducted in the presence of a strong acid catalyst. The formaldehyde is preferably added slowly to nthe reaction nmixture over the course of the reaction. The product can be filtered and dried. |
