Abstract:
A semi-transparent thermoplastic composition having a light transmission, wherein the percentage of light transmission between about 350 nm and about 700 nm is at least 28% of the incident light when measured at a thickness of 0.125 inches, the composition comprising:a) at least about 50% by weight of a poly(phenylene ether) resin based on the weight of the entire composition,b) a non-elastomeric styrenic resin selected from the group consisting of radial block copolymers of butadiene and styrene wherein the styrene content in the copolymers is at least 50% by weight based on the weight of the copolymers, tapered block copolymers of butadiene and styrene wherein the styrene content in the copolymers is at least 50% by weight based on the weight of the copolymers, and mixtures of the foregoing, andc) about 1% to less than 10% by weight of an elastomeric styrenic block copolymer based on the weight of the entire composition, wherein the elastomeric styrenic block copolymer is selected from the group consisting polystyrene-polybutadiene (SBR), poly(.alpha.-methylstyrene)-polybutadiene, polystyrene-polybutadiene-polystyrene (SBS), poly(.alpha.-methylstyrene)-polybutadiene-poly(.alpha.-methylstyrene), and mixtures of the foregoing.
