Mv. Pandya et al., SYNTHESIS AND CHARACTERIZATION OF NYLON-6 TRIBLOCK COPOLYMER USING NEW HYBRID SOFT SEGMENT, European Polymer Journal, 33(6), 1997, pp. 789-794
This paper reports a new method for synthesis of A-B-A type of tribloc
k copolymer of nylon 6 by anionic polymerization route. The A segments
are of nylon 6 units and B segments are flexible soft segments blocks
. These soft segments are b-a-b type cooligomers and are novel. Two se
ries of triblock copolymer of nylon 6 are synthesized. in each series
soft segment B are different. In one series soft segment B is prepared
from amine terminated acrylonitrile butadiene copolymer (Hycar ATBN),
Hexamethylene diisocyanate (HDI), and polyethylene glycol (M-n = 2000
). In the other series, diol is changed to polypropylene glycol (M-n =
2000). Details of synthesis are given. Polymers are characterized by
various spectroscopic techniques. Physical, mechanical and thermal pro
perties of the polymers are also reported. (C) 1997 Elsevier Science L
