| description | 2,2,4-Trimethyl-1,2-dihydroquinoline polymer containing 25% by weight or more of the dimer is effectively prepared by the polymerization of 2,2,4-trimethyl-1,2-dihydroquinoline monomer in the presence of hydrochloric acid, the concentration of hydrochloric acid being from 15 to 25% by weight, and the amount of hydrochloric acid being 0.2 to 0.5 mole per mole of the total of the monomer and impurity amines contained in the monomer. The polymer is useful as an antioxidant for rubber. |
