The invention relates to a cyclodiagenetic polymer, which is obtained by reacting, at temperatures of 150 DEG-170 DEG C. under reflux, 85% of dicyclopentadiene and of the rosin, in molar ratios of 1: 1 to 2 : 1, which then, at 170 DEG-185 DEG C., is reacted with methylene derivatives of alkylphenols selected from (p-tert -butylphenol, p -diisobutylphenol, p -phenylole, amylphenol, bisphenol) : 1 to 1: 0.5 forming multifunctional chromogenic macromonoms, which apoic polycondensation monomers selected from (1,2-ethanediol, 1,2-propanediol, glycerol or pentaerythritol in molar ratios of 5: 0.5 to 5 : 1 at temperatures of 200 ... 240 degrees C makes the polymerization process. |
