An extensive and detailed analysis of copolymers was made by developing a rapid spectrophotometric method. Successful analysis of composition in styrene‐ p ‐methoxystyrene, styrene‐ p ‐chlorostyrene, and styrene‐ p ‐fluorostyrene copolymers were performed by UV spectrometry. Their absorption bands were investigated either with respect to pure polystyrene or with respect to the homopolymer of the other constituent at the same wavelength. Attempts to analyze copolymers of styrene‐4‐vinylpyridine and styrene‐ N ‐vinylcarbazole by similar methods were unsuccessful.
