Title:
RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2020105367
Kind Code:
A
Abstract:
SOLUTION: A resin composition includes a graft polymer (C) obtained by grafting polyolefin (A) with a monomer (B) and satisfies the following requirements (I) to (III): (I) a content of alcohol included in the resin composition measured by head space gas chromatography is 1 μg or more and 1,000 μg or less per 1 g of the graft polymer (C); (II) a graft amount x of the monomer (B) in the graft polymer (C) is 0.5 wt.% or more and 20 wt.% or less with respect to the graft polymer (C); and (III) a relationship between the graft amount x (wt.%) of the monomer (B) and intrinsic viscosity [η] (dl/g) of the graft polymer (C) measured in 135°C decalin satisfies the following expression (i): log10[η]≥0.1-0.15x.EFFECT: The resin composition can be obtained which has a small gel content and an adequate particle diameter. Thereby, efficiency of work of handling the resin composition when being molded or mixed with various resins is excellent, and a problem that fish eye occurs when being processed into a film can be expected to be solved. The resin composition has a high adhesive strength.SELECTED DRAWING: None
