    • 本文利用不同比例之聚乙烯吡咯烷酮(Polyvinylpyrrolidone, PVP)與乙烯基三乙氧基矽烷 (Vinyltriethoxy silane, VTES)在不同比例下共聚合，然後加入聚醚胺 (Polyether amine, PEA) 共混後得一系列PVP-co-VTES/PEA系混摻共聚物。產物內容包含PVP/VTES共聚物及PVP-co-VTES/PEA系混摻共聚物，分別經由相關儀器及檢測，一方面探討共聚物應用於水系之顏料分散可行性；另方面檢測共聚物與PEA混摻後分別與顏料間之分散作用；經由實驗結果顯示，PVP/VTES共聚物皆具有降低表面張力的能力，其中又以PV50的效果最佳。PVP/VTES共聚物在顏料中之粒徑以PV33為最小，亦即PV33具有最佳之分散效果。其次，在PVP-co-VTES/PEA系混摻共聚物方面，其粒徑則隨PVP用量之減少而減少，而分散力則隨之增加，其中又以PV50D分散效果最佳，PV16D則最差。另外，一系列之PVP-co-VTES/PEA系混摻共聚物對三種顏料之分散效果皆比PVP/VTES系共聚物之分散效果佳。無論PVP/VTES共聚物或PVP-co-VTES/PEA系混摻共聚物對顏料於水中之分散效果皆隨濃度及之增加而提升。最後，PVP/VTES共聚物與其混摻共聚物等兩種分散劑對顏料之分散效果呈不同之順序，前者以PV33最好，後者以PV50D最佳。

    In this paper, the copolymer of polyvinylpyrrolidone (PVP) and vinyltriethoxy silane (VTES) was prepared and then mixed with polyether amine (PEA) to obtain a series of PVP-co-VTES/PEA blending copolymers. The product includes PVP/VTES copolymers and PVP-co-VTES/PEA blending copolymers which are detected by relevant instruments respectively. This experiment discusses the dispersion feasibility by applying copolymers into aqueous pigment; on the other hand, it detects the dispersion between copolymers and pigment or between PEA and pigment after their blending. The experimental result shows all PVP/VTES copolymers have the ability to reduce the surface tension, of which, the effect of PV50 is the best. The grain size of PV33 among PVP/VTES copolymers in pigment is the minimum. That is, PV33 has the best dispersion effect. Then, the grain size of PVP-co-VTES/PEA blending copolymers decreases with the reduction of PVP dosage, but the dispersion force increases, of which, the dispersion effect of PV50D is the best, but that of PV16D is the worst. In addition, the dispersion effect of a series of PVP-co-VTES/PEA blending copolymers on three pigments is better than that of PVP/VTES copolymers. The dispersion effect of both PVP/VTES copolymers and PVP-co-VTES/PEA blending copolymers on aqueous pigment increases with the increase of concentration. Finally, the dispersion effect of two dispersants PVP/VTES copolymers and their blending copolymers on pigments are in reverse order. PV33 in the former is the best while PV50D in the latter is the best.
