From previous embodiment as can be seen, the composition that contains polyvinyl chloride, polyoxymethylene or the urethane of 0.5wt% has and matrix resin surpasses the physicals of 20% difference.20 percent physicals difference is enough to make composition not to be suitable for the application that many base resins are suitable for.
Previous embodiment has confirmed to contain the effect of the 3rd thermoplastics of 4-5wt%, and described the 3rd thermoplastics is polypropylene, acrylonitrile-butadiene-styrene copolymer, polycarbonate, polycarbonate/acrylonitrile-butadiene-phenylethene copolymer blend, polymethylmethacrylate, polymeric amide, polybutylene terephthalate and polycarbonate/polybutylene terephthalate blend for example.In every kind of situation, with respect to base resin, the combination table of single physicals or two kinds of physicalies reveals 15% or bigger variation.20% or bigger variation of physicals can be so that material be suitable for many application.In certain embodiments, 15% of two kinds of physicalies combination changes and can produce adverse influence on the suitability of some application to composition.
In addition, previous embodiment has also confirmed to contain the effect of metal and metallic compound.Also can produce remarkable influence even contain a spot of metallic compound to the physicals of composition.Each embodiment shows that 15% combination on two kinds of physicalies changes and/or 20% variation on the single one physical performance.As previously mentioned, the value of these variations can be so that material be unsuitable for many application.
In the recycled thermoplastic compositions that contains poly-(arylene ether), aforementioned polymer exists separately or with the form that makes up no matter be, all can influence the physicals of this recycled thermoplastic compositions, therefore on the cycle industrial of thermoplastics, can draw such dominant ideas: in order to be applied to the common purposes of fresh resin, the recycled thermoplastic plastics must be highly pure.Different with above-mentioned dominant ideas, the recycled thermoplastic plastics can comprise the second quite high thermoplastics of content, and have still kept the physicals distribution similar substantially to fresh material.
Although invention has been described with reference to exemplary embodiment, it will be understood by those skilled in the art that do not breaking away from the scope of the invention that the present invention can make various variations and can replace with equivalent.In addition, do not breaking away from the scope of the invention, according to the instruction of this specification sheets, in order to adapt to specific occasions or material, the present invention can make multiple variation.Therefore, the present invention be not limited to be used to explain the present invention, as the specific embodiment of preferred forms, but be included in all embodiments in the scope of appended claims.
