摘要：
A computer program called MSCOPOL has been developed to aid in the interpretation of copolymer mass spectra. The program reads the mass spectrum, calculates the most likely monomer masses via correlation or Fourier transform methods, determines possible end group masses based on the monomer masses, and can then search monomer and end group data bases for likely chemical moieties. Refinement of the end group result is possible by calculation of the monomer ratio and degree of polymerization as a function of end group mass. The program is written in Microsoft Visual Basic and runs on an IBM compatible PC. Applications are shown for polystyrene, poly(N-vinyl pyrrolidone/vinyl acetate), and poly(ethylene oxide/propylene oxide).
