Stabilization of rosin dispersions with low molecular weight non-ionic
polymers
摘要:
Low molecular weight, non-ionic copolymers of acrylamide and a monomer selected from the group consisting of styrene, alkyl (C.sub.4 -C.sub.24) substituted acrylamides and ethylene provide improved mechanical and heat stability to colloidal aqueous rosin dispersions.
