โœฆ Synopsis

The opt&l spectra of fully and parthl!y polymerized crystals of ~is(p-tolucne sulphonatc) diacctylcnc have been mnsurcd between 4.2 and 330 K. The electronic absorption of the conjugated polymer bxkbone occurs at about 2 CV and is split into two components below 160 K in both fully and partinlly polymerized smpler The origin of thic splitting is dis-

Ihe pyrociectric properties of the monomer and pztially end fufty polyme~d crystals of the ~~tolu~nc ~lphon3te) of 2,4-hexa&yne-l&diol (TS) were measured along their b axes from tOO to 300 K T-o peaks in the pyroclcctnc current or monomer crystals were found at 192 and 15 1 K. It is concluded that t
