Abstract
Using a renormalization group method of analysis of series, in which the order of truncation plays the role of a scale parameter, we study accurate Monte Carlo enumerations for SAW with attractive n.n. interaction on the square lattice. The theta point is located and its exponents are determined as νt = 0.570 ± 0.015, γt = 1.10 ± 0.04 and Φ t = 0.52 ± 0.07. These values are compared with others previously proposed in the literature, and seem to support recent theoretical conjectures
