The obtained results were spectras of single copolymer/homopolymer and blends. the analysis of MALDI-TOF spectras were successfully analyzed by an algorithm called Multistep Mass-Remainder Analysis (M-MARA). Multi-Step Mass Remainder is based on sequential calculations of the remainder in order to eliminate the periodicities present in a complex system. And then provides highly simplified plots that can easily reveal if the analyte is a single copolymer/homopolymer or a blend.27enpolyether polyols (polymer)DEENK Témalista::Kémia
