INFLUENCE OF ZnSt2 ON STRUCTURE OF ACRYLATE-BASED IONOMERS WITH DIFFERENT LANTHANIDE (La(III)) ION AND ACID CONTENTS
A series of acrylate processing aid (ACR)-based ionomers with different lanthanide (La(III)) ion and acid contents were synthesized
and the interaction between ionomer and zinc stearate (ZnSt
2
) was investigated immediately after thermally annealing the ionomer/ZnSt
2
(3/1 in weight) mixtures at 180℃. The results revealed that the ion groups in ionomer have a strong interaction with ZnSt
2
. The annealed mixtures contained hot alcohol extractable and unextractable ZnSt
2
. The melting of ZnSt
2
and the thermal behavior of the ionomer in the annealed mixtures were seriously influenced by the contents of La(III) and acid in the ionomers. The ionomer containing 0.25 mmol/g acid and 0.37 mmol/g La(III) has a detectable cluster phase. Annealing its ZnSt
2
mixture could break down the cluster phase and lower glass transition temperature of the ionomer matrix. However
washing away the extractable ZnSt
2
led to the reappearance of the cluster transition temperature and return of the glass transition temperature of matrix to the original position.
