Kinetics of ring-formation and polymerisation in solution

(Received 9th August, 1935.) (Received 9th August, 1935.) In a series of experiments carried out by H. Freundlichl and his co- workers, the kinetics of the reaction Br . CH, .(CH,), .NH, -+ CH, .(CH,),NH, HBr (Cl. I) I I (Cl. I) were investigated by measuring the increase of the halogen ion concen- tration,
