Because of the extensive crystallisation, even in the copolymers, high strengths are achieved even though the molecular weights are quite low (-20000-50000). A typical 85 15 copolymer plasticised with diphenyl ethyl ether has a melting point of about 170°C, a glass temperature of about - 17°C and a maximum rate of crystallisation at approximately 90°C. ...

The effect of penultimate units on the rate constants of anionic propagation is observed also in other systems. For example, the addition of styrene to the lithium salt of 1-phenyl-n-hexyl anion is 4 times faster than to polystyryl lithium 51). Similarly, the addition of monomer to the lithium salt of 1,1-diphenyl-n-hexyl lithium is faster than the addition to 1,1,3-triphenyl-n-octyl lithium or 2-poly-sty ry 1-1,1-diphenyl ethyl lithium, the latter two salts having comparable reactivities52 .

Materials. Chemically pure solvents and reagent grade ceric ammonium nitrate were used as received. Cumene hydroperoxide was purified via the sodium salt. Lucidol tert-butyl hydroperoxide was purified by low temperature crystallization. Tetralin hydroperoxide, cyclohexenyl hydroperoxide, and 2-phenylbutyl-2-hydroperoxide were prepared by hydrocarbon oxidation and purified by the usual means. 1,1-Diphenyl-ethyl hydroperoxide and triphenylmethyl hydroperoxide were prepared from the alcohols by the acid-catalyzed reaction with hydrogen peroxide (10).

In contrast, the 1,1-diphenyl ethyl cation (92) is unreactive to benzene. This indicates that the carboxonium group (or the corresponding acyl ion) participates in the superelectrophilic activation of the adjacent carboca-tionic center. [Pg.247]
