OLEFIN-based ionomer resin composition

摘要

The present application relates to an olefin-based ionomer resin composition, to an encapsulant, and to an optoelectronic device. The resin composition according to the present application may be used as an encapsulant for a variety of optoelectronic devices, and may exhibit superior adhesion to the substrates of the optoelectronic devices. In addition, according to the present application, an olefin-based ionomer resin composition, which can provide good workability and economic advantages in the manufacture of devices without negatively affecting components such as encapsulated optoelectronic elements or the wired electrodes of optoelectronic devices, may be provided.

1. An olefin-based ionomer resin composition comprising:
a modified olefin copolymer having two or more functional groups which includes a carboxyl group, wherein the modified olefin copolymer is a graft copolymer in which an ethylenically unsaturated silane compound as a first monomer and a monomer having an ethylenically unsaturated double bond as a second monomer are grafted to a polyolefin having a density of 0.85 g/cm3 to 0.96 g/cm3, and a part or whole of the carboxyl group in the olefin-based ionomer resin composition is neutralized with metal ions.
