A poly(p-methylstyrene)-block-polyisoprene-block-poly(p-methyl styrene) thermoplastic elastomer was synthesized via anionic polymerization using n-butyllithium as an initiator. The sequential method used for the synthesis has resulted in a nearly monodispersed polymer with a polydispersity of 1.02.
The methyl groups of soluble and 1% crossfinked poly(p-methylstyrene) were chlorinated in mixtures of chloroform and aqueous sodium hypochlorite that was neutralized to pH 8.4 with HCI, both in the presence and in the absence of the phase-transfer catalyst (P TC) benzyltriethylammonium chloride.

Poly(p-chlorostyrene), PCSt, and poly(p-chloro-a-methylstyrene), PCaMSt, are much less photosensitive than low molecular model compounds. The quantum yield of HCI formation $(HCI) -0.01 is much lower than 4(HCI) -0.18 determined for I-chloro-4-isopropylbenzene and l-t-butyl-4-chlorobenzene. The pre
