Typical
Nylon 6 Modification by Tuftec™ M
As indicated by these
two microgrhaphs of modified nylon 6 (PA6) obtained under
the same blending and extruding conditions,
the Tuftec™ M series enables the formation of significantly
smaller dispersed particles than the Tuftec™ H series,
and far higher impact strength.
This is attributable to the formation of a graft structure,
by the reaction of the Tuftec™ M acid anhydride groups
with the PA6 functional end groups.
SEM micrographs of PA6/elastomer (80/20) sample cross-sections
obtained by fracturing in liquid nitrogen and etching
in toluene
to remove elastomer; H1041
is a Tuftec™ H series elastomer, containing no acid
anhydride groups.

PA6/H1041
Izod impact strength 5 kgcm/cm
|
PA6/M1913
Izod impact strength 85 kgcm/cm
|
|
As shown here, the maximum impact strength can
be obtained by optimization of the dispersed particle
size, which is dependent on the PA6 end-group,
the functional group content of the Tuftec™
M, and the blending and extruding conditions.
