PROCESS FOR THE PREPARATION OF STRUCTURALLY DYED POLYESTER RESINS |
| 摘要 |
Disclosed is a process for the preparation of structurally dyed polyester resins by polycondensation of phthalic anhydride, pentaerythritol and pigments. Pentaerythritol is modified with pigments of benzene and naphthalene series comprising carboxyl groups. Phthalic anhydride is loaded, and condensation is performed at given temperature up to preset acid number at molar ratio of phthalic anhydride : pentaerythritol as 2:1:2. |
