Abstract
Polyamide resins characterized in melt state by high sensitivity to shear forces and high visco-elasticity, obtained by polycondensation/polyaddition in the solid state in presence of polyfunctional compounds capable of reacting with resin terminal groups and/or in presence of polyester resins employed in quantity up to about 40% by weight of the resin mixtures.
