The Mark-Houwink equations relating the intrinsic viscosity of poly(trimethylene terephthalate) to its number and weight average molecular weights in two solvents are reported. Several simplified equations for single-point measurements are evaluated. The limit and accuracy of applicable equations are discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.
