Title:
POLYARYLENE SULFIDE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/022023
Kind Code:
A1
Abstract:
Provided is a polyarylene sulfide composition that is excellent in weld strength, heat cycle resistance, mold flowability and thin-wall flowability without deterioration in heat resistance, chemical resistance, dimensional stability, etc. The polyarylene sulfide composition comprises, per 100 parts by weight of a polyarylene sulfide (A) having a melt viscosity of 100-2000 poises when measured by a Koka flow tester provided with a die (diameter: 1 mm, length: 2 mm) at a measurement temperature of 315°C under a load of 10 kg, a modified ethylene copolymer resin (B) comprising (B1) or (B2) as follows and 15-100 parts by weight of a fibrous filler (C).
(B1) 1-12 parts by weight of an ethylene-α,β-unsaturated carboxylic acid glycidyl ester-α,β-unsaturated carboxylic acid butyl ester copolymer.
(B2) 1-30 parts by weight of at least one modified ethylene-based copolymer selected from an ethylene-α,β-unsaturated carboxylic acid alkyl ester-maleic anhydride copolymer and a maleic anhydride graft modified ethylene-α-olefin copolymer and 0.1-3 parts by weight of isocyanurate, wherein the ratio of the isocyanurate/the modified ethylene-based copolymer(s) (parts by weight/parts by weight) falls within the range of 0.05-0.3.
