Novel retention aids for mechanical pulps
Abstract
Acrylamide and poly(ethylene glycol) macromonomer copolymers, in conjunction with phenolic formaldehyde resin (PFR), were evaluated as novel retention aids for newsprint pulps. The first-pass retention of the pulp fines was increased from 37% without polymer to nearly 90% with copolymer addition. This retention performance was similar to that of the high molercular weight polyiethylene oxide) (PEO)/phenolic resin dual-polymer systems. However, …
