โฆ Synopsis
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 these crystals lack a ccntre of symmetry.
