摘要:
There is disclosed a thermoplastic resin composition comprising a blend of 100 parts by weight of a resin composition composed of 1 to 99% by weight of a polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aroamtic monomer onto polypropylene, and a composition composed of the modified polypropylene (A) and a polypropylene (B), and 99 to 1% by weight of at least one sturated polyester resin (D), 0.1 to 300 parts by weiht of an epoxy group containing copolymer (E), 0.1 to 300 parts by weight of a modified ethylenic copolymer ruber (F) obtained by graft copolymerizing and an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto ethylenic copolymer ruber, and Up to 5 partsg by weight of a basic comdpound (G) optionally added as reaction accelerator, the content of the saturted polyester resin in the thermoplastic polyeste4r resin being less than 50% by weight. The thermoplastic resin composition of the present invention has high heat resistance and high impact resistance. in particular, high low-temperatuer impact resistance and is advantgeously used in automobilde parts, electric and electronic parts, etc.
摘要:
A thermoplastic resin composition which contains a resin composition containing a crystalline polypropylene component, an ethylene-butene-1 copolymer rubber and an ethylene-propylene copolymer rubber; a modified polypropylene; a saturated polyester resin; and an epoxy group-containing copolymer; and optionally talc exhibits high low-temperature impact strength, stiffness and Rockwell hardness and a small coefficient of linear expansion, which composition gives an injection-molded article suitably used for a bumper for automobile.

摘要:
Provided are a filament winding method and a filament winding apparatus, in which, when a new bobbin (10) is mounted on a bobbin rotation driving device (20), the control device (60) rotates the bobbin to oscillate a dancer (30) while maintaining a state where a distal end of filament (11) unwound through the dancer is fixed further beyond the dancer and the filament is stretched. The control device obtains a bobbin diameter of the bobbin mounted on the bobbin rotation driving device based on a length (LD) of the dancer, an oscillation angle (θ1) of the dancer, and a rotation angle (θa) of the bobbin.
(A) 1 to 99 % by weight of a polyphenylene ether resin, (B) 99 to 1 % by weight of a polystyrene resin obtained by copolymerisation of a styrene compound, 100 to 500 ppm by weight of a compound containing a plurality of vinyl groups, and if necessary, a compound copolymerisable with the styrene compound, and/or a polystyrene resin obtained by copolymerisation of a styrene compound, 100 to 500 ppm by weight of a compound containing a plurality of vinyl groups, a rubber, and if necessary, a compound copolymerisable with the styrene compound, and having a weight average molecular weight of 150 thousand to 1 million and a number of branching points in a Z-average molecular weight of 2 to 20, and (C) 0 to 100 parts by weight of a rubber per 100 parts by weight of the total amount of (A) and (B) [wherein, when (B) contains a rubber, said weight of (B) is the weight excluding the weight of said rubber].
According to the present invention, the thermoplastic resin composition having an excellent flowability and an excellent appearance of a molded article obtained can be provided.
