The modification of nylon 6 by a phenol-formaldehyde resin

Modification of nylon 6 by blending with a small amount of a novolac resin has been investigated. Unexpected increased of T_g and tensile modulus and reduction in moisture absorption have been found at levels of novolac incorporation of 1–3 wt %. The small amount of novolac resin also has an effect on the crystallization and nylon 6 crystal structure (α vs. γ form). © 1993 John Wiley & Sons, Inc.
