M. Marek et al., SYNTHESIS AND PROPERTIES OF COPOLYMERS CONSISTING OF ARAMIDE AND POLY(6-HEXANELACTAM) BLOCKS, European Polymer Journal, 31(4), 1995, pp. 363-368
Low molecular weight aromatic polyamides of the meta-type which bear N
-acyl-6-hexanelactam end-groups were prepared, characterized by NMR an
d utilized as initiators of the anionic polymerization of 6-hexanelact
am. The resulting block copolymers poly(6-hexanelactam)-block-poly(iso
phthalic -1,3-phenylenediamine)-block-poly-(6-hexanelactam) were chara
cterized by NMR, DSC, TGA, X-ray diffraction and microscopy of solutio
n-cast films and compared with an aramide-polyamide 6 blend also prepa
red by polymerization.
