<p>PURPOSE:To remarkably improve adhesive properties with a lead frame without reducing mechanical properties without almost generating decomposed gas or deposited gas with high thermal stability by mixing polyarylene sulfide resin as a main ingredient, alpha-olefin copolymer graft-copolymerized with unsaturated carboxylic acid or its anhydride, and inorganic filler at a special ratio. CONSTITUTION:0.1-30 pts.wt. of alpha-olefin copolymer graft-polymerized with unsaturated carboxylic acid or its anhydride and 10-300 pts.wt. of fibrous filler, nonfibrous inorganic filler or mixture of both are mixed with 100 pts.wt. of polyarylene sulfide resin. The resin is not particularly limited, polymer of oxide crosslinking or thermal crosslinking may be used, and desirably polymer of substantially linear molecular structure having low crosslinking degree obtained by condensation polymerization from bifunctional monomer may be used. It is particularly desirable to use unsaturated carboxylic acid or its anhydride of maleic acid anhydride having 1.0-5.0% of graft rate.</p> |
