    Notes: Abstract CdTep-n junction diodes were prepared by LPE using CdCl2 as a solvent. Excess cadmium was added to the CdCl2-CdTe solution. Capacitance-voltage characteristics show that the diode structure is ofp-i-n type. Injection electroluminescence spectra reveal that radiative transitions occur mainly in thep-type region; relevant recombination centers are discussed in connection with those in a previous paper on the photoluminescence of CdTe:P crystals. Temperature dependences of the electroluminescence spectra were explained taking into account a change in sites where electrons radiatively recombine.

    Cationic polymerization α,β-disubstituted olefins. Part I. Cationic copolymerization of β-methylstyrenes (1965)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A: General Papers 3 (1965), S. 2567-2578

    Notes: Steric and electronic effects of the β-methyl group on monomer reactivity have been studied by copolymerization of styrenes and β-methylstyrenes. Steric hindrance of the β-methyl group in the transition state of homopolymerization is so great that the rate of the propagation reaction is considered to be depressed by as much as 1/10-1/20 of the corresponding styrene derivatives. In contrast to this, steric hindrance of the β-methyl group in cross propagation reactions with styrene is found to be very small. The monomer reactivity itself of β-methylstyrenes is a little lower than that of corresponding styrenes. This lowered reactivity of β-methylstyrenes is considered to be due to the electronic effect of the β-methyl group.
