Title:
IONOMER RESIN COMPOSITION AND MOLDED ARTICLE THEREOF
Document Type and Number:
Japanese Patent JP2020158682
Kind Code:
A
Abstract:
To provide an ionomer resin composition capable of molding a molded article excellent in dimensional stability and transparency under high temperature environment and having excellent molten fluidity.SOLUTION: There is provided an ionomer resin composition obtained by reacting an olefin polymer (A) having 10 mol% or more of a constitutional unit derived from a cyclic olefin and at least one functional group (fg) selected from an acid group and an acid anhydride group with a metal compound (B), wherein a neutralization index (%) represented by the following expression is 0.01 to 40%. Neutralization index (%)=(the valence of the metal ion of the metal compound (B))×(the content (mole number) of the metal ion of the metal compound (B))÷(the content (mol number) of the functional group (fg) in the olefin polymer(A))×100.SELECTED DRAWING: None
