A software

which can demonstrate binary copolymer composition curves of polymer chemistry

is programmed via using Matlab. The visualization of copolymer composition

including instantaneous copolymer composition

average composition and segment sequence distribution

can be achieved only by inputting the reactivity ratio or Q and e values. This software is simple enough to be used

which not only can be used for classroom teaching but also can be practiced by the students after class. It is a powerful computer-assisted instructive tool.
