✦ Synopsis

Acenaphthylene was polymerized in methylenedichloride at 273, 291 and 308 K by sulphuric acid. The initiation step takes place by addition of the proton of sulphuric acid to the monomer. The propagation step is through ion-pairs, and the propagation constants are first-order with respect to the monomer and initiatgr(k,=0 22 M-I.s-I(273K), k =0.88 M-I.s-I(291K), k = 2.81M-1.s-l(30~K)i. There is not appreciable loss of active P centres, being this confirmed by experiments carried out with succesive additions of monomer. The molecular weights obtained confirm the importance of processes to monomer in this polymerization.
