Abstract:

A phenolic polymer has been polymerized under conditions which lead to a crack free solid casting and its compressibility, electrical resistivity and specific heat have been determined. A secondary transition was found by compressibility measurements at about 120C and its existence confirmed by resistivity and specific heat measurements. Based upon the experimental data it is estimated that a glass transition would occur in this polymer at about 325C if degradation did not occur. The secondary transition is discussed in terms of polymer structure.
