| Abstract | The copolymers of N-vinyl-2-pyrrolidone (N-VP) and condensation cardo and/or fluorinated condensation polymers (aromatic polyamide, polyimide and polyarylate) were-synthesized by free radical in situ polymerization. The partial formation (14-61 wt%) of polivnylpyrrolidone (PVP) homopolymer upon the polymerization of N-VP containing dissolved condensation polymer was stated. Synthesized (co)polymers are differed in heat resistance and solubility from neat PVP. Using relevant copolymers solutions in N-methyl-2-pyrrolidone the optical fiber coatings having good adhesion properties were fabricated. Such coatings demonstrate high stability at elevated temperatures. A substantial number of defects on coatings and a slight decrease in bending strength are observed only on exposure at 200 degrees C for 72 h. Simultaneously holding for 1 and 24h at the same temperature leads to hardening of the fibers: bending strength changes from similar to 5 up to 6 GPa. (C) 2016 Elsevier B.V. All rights reserved. |
