Abstract: | The viscosity of high and low crystallinity samples of homopolymer and copolymer polyformaldehyde were studied in the low temperature region at subaudible frequencies. On the basis of the data received, suggestions regarding the low temperature relaxation of polyformaldehyde are put forward.T. G. Shevchenko State University, Kiev.
