Compositions comprising polyphosphonates and additives that exhibit an advantageous combination of properties, and methods related thereto
View Patent ↗Disclosed are new compositions consisting of polyphosphonates and specific additive compositions that exhibit superior resistance to degradation due to exposure to air, high temperature and air, moisture or combinations thereof. Also disclosed are polymer mixtures or blends comprising these polyphosphonates/additive compositions and commodity and engineering plastics and articles produced therefrom. Further disclosed are articles of manufacture produced from these materials, such as fibers, films, coated substrates, moldings, foams, fiber-reinforced articles, or any combination thereof.
1. A polymer composition comprising:
one or more high molecular weight polyphosphonates; and
at least one additive selected from the group consisting of:
and combinations thereof.
2. The polymer composition of claim 1 , wherein the additive is selected from:
and combinations thereof.
3. The polymer composition of claim 1 , wherein the concentration range of the additives is from about 0.01 to 1.0 percent by weight.
4. The polymer composition of claim 1 , wherein the polyphosphonates are linear.
5. The polymer composition of claim 1 , wherein the polyphosphonates are branched.
6. A polymer blend or mixture, comprising:
at least one polyphosphonate/additive composition according to claim 1 ; and
at least one other polymer.
7. The polymer mixture or blend of claim 6 , wherein said at least one other polymer is selected from polycarbonate, polyacrylate, polyacrylonitrile, polyester, polyamide, polystyrene, high impact polystyrene, polyurethane, polyepoxy, poly(acrylonitrile butadiene styrene), polyimide, polyarylate, poly(arylene ether), polyethylene, polypropylene, polyphenylene sulfide, poly(vinyl ester), polyvinyl chloride, bismaleimide polymer, polyanhydride, liquid crystalline polymer, polyether, polyphenylene oxide, cellulose polymer, and combinations thereof.
8. The polymer mixture or blend of claim 6 , wherein said at least one other polymer comprises polycarbonate.
9. An article of manufacture produced from the polyphosphonate/additive composition of claim 1 .
10. An article of manufacture produced from the polymer mixture or blend of claim 7 .
11. The article of manufacture of claim 9 , wherein the article is a fiber, a film, a coating, a molding, a foam, a fiber reinforced article, or combination thereof.
12. The polymer mixture or blend of claim 7 , wherein the article is a fiber, a film, a coating, a molding, a foam, a fiber reinforced article, or any combination thereof.
