Monomeric and polymeric pigments from polystyrene were prepared. Polynitrostyrene and polyaminostyrene were used as intermediates. The structure of these intermediates were identified by Infrared spectroscopy and Elemental analysis. Polyaminostyrene was diazotized in dispersion state, and then coupled with ο-acetoacetotoluidide, 4-chloro-2,5-dimethoxy-anilide, 3-methyl-1-phenyl-5-pyrazolone, 2-naphthol, 2-hydroxy naphthanilide. The colors of these pigments were determined by the color computer. The light resistance, heat resistance, and solvent resistance of polymeric pigments were investigated. The properites of the polymeric pigments were compared to those of monomeric pigments.

폴리스티렌을 기질로 하는 몇 가지 저분자 및 고분자 안료를 합성하였다. 중간체로서는 폴리니트로스티렌과 폴리아미노스티렌을 사용하였고 중간체들의 구조는 적외선 분광법과 원소분석에 의해 확인하였다. 폴리아미노스티렌은 분산상태로 디아조화시킨 후 아세토아세토톨루이디드, 4-클로로-2,5-디메톡시아세토아세타닐리드, 3-메틸-1-페닐-5-피라졸론, 2-나프톨, 2-히드록시 나프타아닐리드로 커플링시켰다. 이러한 안료들의 색은 컬러컴퓨터(color computer)로 결정하였다. 얻어진 고분자안료들의 내광성, 내열성 및 내용매성을 조사하고 저분자안료들의 물성과 비교검토하였다.
