Zusammenfassung:The invention provides a method of efficiently producing branched, cyclic glycerol-based polymer surface active products having ester and alkyl functional groups with a co-product as anti-biodegrading agent from inexpensive readily available glycerol monomer. The method involves polymerizing glycerol or glycerol with at least another monomer to multiple other monomers in the presence of particular amount of a strong base as the catalyst under a particular distillation environment. The polyol then undergoes esterification, alkylation and crosslinking in presence of particular amount of a catalyst under a particular low activity atmospheric environment. The glycerol-based polymer surface active products produced by the inventive method are beneficial for reducing lignin, extractives and rejects levels in pulping process of papermaking industry.
