Synthesis and Study of Organosoluble Aromatic Cardo (co)polyamides and Their Application in the Optical Fiber Primary Coating Technology
A series of organosoluble aromatic cardo copolyamides (PA) with chlorine and carboxylic side groups has been synthesised by low‐temperature polycondensation in N‐methyl‐2‐pyrrolidone (N‐MP) solution and their properties have been estimated. The obtained polymers are differed in high molar masses (ηi...

description | A series of organosoluble aromatic cardo copolyamides (PA) with chlorine and carboxylic side groups has been synthesised by low‐temperature polycondensation in N‐methyl‐2‐pyrrolidone (N‐MP) solution and their properties have been estimated. The obtained polymers are differed in high molar masses (ηinh = 0.7 ÷ 1.8 dL/g) and demonstrate the following thermal characteristics: 300 °C |
