MEHRSTUFENPOLYMERE

摘要

Formation of a radiation-curable, multistaged latex polymer, comprises (a) forming a multistage latex polymer comprising (1) a first stage polymer; and (2) a second stage polymer comprising at least one comonomer contg. acid functionality; (b) partially neutralising the acid functionality of the second stage polymer of the second stage polymer with a base; and (c) reacting the partially neutralised polymer with a monoethylenically unsatd. epoxide cpd. A quat. ammonium phase transfer catalyst is pref opt. added before step (c).
