A single crystal mat of polyoxymethylene (POM) is compressed hydrostatically up to 20 kbar at 25℃. The lattice constants of trigonal form of POM are measured and found to vary reversibly with pressure; a-axis is decreased by about 5.5% and c-axis, 0.3% at 20kbar. Equation of state of the trigonal form of POM is calculated under the approximation of a two-dimensional lattice; intra-chain configuration is assumed to be unchanged. The agreement between the calculation and the experiment is found to be good for two possible space groups, P3_121 and P3_112. The transformation from the trigonal to the orthorhombic form is discussed. Four elastic compliances, s_<11>, s_<12>, s_<13> and s_<33> are also obtained.
