Use of biobased sugar monomers in vinyl copolymers as latex binders and compositions based thereon

摘要

The present invention provides the novel and nonobvious discovery that sugar macromers can be effectively used to provide a new generation of renewable comonomers for bio-synthetic hybrid paper binder systems having a controlled hydrophilic-hydrophobic balance for improved water retention and film forming properties, on machine runnability, offset printability, biodegradability, enhanced recyclability, and other performance attributes.

主权项

1. A method of preparing a paper coating comprising copolymerization of a vinyl-substituted alkyl polyglycoside with vinyl comonomers via a water based polymerization process to produce sugar based copolymers having a dry glass transition temperature (Tg) ranging from −10 to 50° C. and a Tg in the wet state ranging from −40 to 45° C. and forming a mixture comprising particles of the sugar based copolymers and a pigment in water.
