一种含有PPO-PEO与PDMS的多嵌段共聚物在制备改性有机颜料中的应用
Abstract:
本发明公开了一种含有PPO‑PEO与PDMS的多嵌段共聚物在制备改性有机颜料中的应用，所述含有PPO‑PEO与PDMS的多嵌段共聚物为线性无规多嵌段共聚物，具有式(I)所示重复结构：式(I)中：m、n、x均为正整数；x为10～15；n为10～15；m>n+x。本发明提供的含有PPO‑PEO与PDMS的多嵌段共聚物在制备改性有机颜料中的应用，所述含有PPO‑PEO与PDMS的多嵌段共聚物能改善有机颜料的分散性，在不同的应用体系中，均能改善颜料油墨的色相、光泽及透明度，使其色相朝着绿相迁移，同时大幅度地提升颜料油墨的色力。
Abstract(English):

The invention discloses application of a segmented copolymer containing PPO-PEO (Poly Phenylene Oxide-Polyethylene Oxide) and PDMS (Polydimethylsiloxane) in preparation of modified organic pigments. The segmented copolymer containing PPO-PEO and PDMS is a linear random segmented copolymer and has a repetition structure shown as a formula (I), wherein the structural formula is as shown in the description. In the formula (I), m, n and x are positive integers; x is 10-15; n is 10-15; m is more than n+x. According to the application of the segmented copolymer containing PPO-PEO and PDMS in preparation of modified organic pigments provided by the invention, the segmented copolymer containing PPO-PEO and PDMS is capable of improving dispersity of the organic pigments, the hue, gloss and transparency of pigment ink can be improved in different application systems, the hue migrates to a green phase, and the coloring power of the pigment ink is greatly improved.
