Title:
POLYOLEFIN COPOLYMER, RESIN PELLETS, MODIFIER FOR ENGINEERING PLASTIC, ENGINEERING PLASTIC COMPOSITION, AND RESIN MOLDED BODY
Document Type and Number:
Japanese Patent JP2023170477
Kind Code:
A
Abstract:
To provide a polyolefin copolymer that is used as a modifier for engineering plastic to yield an engineering plastic composition with low dielectric constants and low dielectric loss tangents.SOLUTION: A polyolefin copolymer has a main chain containing a monomer unit A derived from a C2-8 olefin monomer and a monomer unit B having a glycidyl group. The main chain may also contain a monomer unit C derived from a (meth)acrylic acid ester or vinyl ether. Based on the mass of the olefin copolymer, the proportion of the monomer unit A is 94 mass% or more and the total proportion of the monomer unit B and the monomer unit C is less than 6 mass%.SELECTED DRAWING: None
