Claims26
A low-gloss thermoplastic resin composition with good resistance to heat and weather, comprising:
- (A) a thermoplastic resin forming a first dispersed phase, and
- (B) an acrylic resin forming a second dispersed phase,
- wherein the first dispersed phase has a network configuration, wherein the (A) thermoplastic resin comprises (a1) an alkyl (meth)acrylate polymer forming a dispersed phase in a network configuration, and (a2) an aromatic vinyl-vinyl cyanide copolymer forming a continuous phase.
A molded article having a morphology of continuous phase and dispersed phase,
- wherein the continuous phase comprises an aromatic vinyl-vinyl cyanide copolymer and a heat resistant aromatic vinyl copolymer;
- the dispersed phase consists of a first dispersed phase in a network configuration and a second dispersed phase in the form of particles;
- the first dispersed phase is formed from an alkyl (meth)acrylate polymer;
- and the second dispersed phase is formed from an acrylic resin,
- wherein the molded article has a notched Izod impact strength of about 8 kg·cm/cm or more as measured at a thickness of ⅛″ by ASTM D256, and a Vicat softening temperature of about 100 to about 150° C.
