Abstract
Differences have been observed between the ultraviolet absorption of certain styrene statistical copolymers and that of the corresponding mixtures of homopolymers. These effects are a function of the chemical nature and position of the substituent on the benzene ring.Analysis of the result obtained shows that the ultraviolet abscrption of styrene statistical copolymers depends on the tendency of the two monomeric units to be linked alternately along the binary copolymer chain and on the chain conformation, which in turn may favor or hinder, to a greater or lesser extent, electronic interactions between neighboring chromophore groups.
