Experimental Substantiation of the Model

Experiments were carried out with IB and St, arguably the two most important representative olehns polymerizable by cationic means. Polymerizations were initiated by the purposely added initiator 2-chloro-2,4,4-trimethylpentane (TMPCl) or by adventitious moisture, H2O (i.e absence of purposely added initiator), in conjunction with TiCU under various conditions specified in the legends to the figures and tables. The raw data are collected in tables shown in the Appendix. This section concerns the presentation of the data and their interpretation in terms of the model developed in Sect 2.
