Sulfonated polyphosphazene copolymer proton exchange membrane material and method for preparing such membrane
A sulfonated polyphosphazene copolymer proton exchange membrane material, and a method for preparing such membrane includes a macromolecule initiator as bromo polyphosphazene is subjected to atom transfer radical polymerization with styrene, yielding a graft copolymer, which is hydrazinolyzed with hydrazine hydrate resulting in a copolymer including a hydroxyl group. The copolymer is reacted with 1,4-butane sultone to yield a sulfonated copolymer finally. The polymer is cross-linked with 2,6-di(hydroxymethyl)-4-methyl phenol (BHMP) as a cross linking agent in the presence of methyl sulfonic acid, yielding cross-linked proton exchange membrane. Such cross-linked graft copolymer membrane has high proton conductivity, low methanol hindrance, and low cost, and has ideal effect when applied in fuel cells as proton exchange membrane material.

Flame retardant polylactic acid compounds
A significant disadvantage of the use of polylactic acid (PLA), lack of flame retardance, has been overcome by the use of specific combinations of either polycarbonate or polyphosphonate-co-carbonate in combination with non-halogenated flame retardants of polyphosphazene or phosphate ester such as resorcinol bis (diphenyl phosphate) or metal hypophosphite, a drip suppressant, and optionally an inorganic synergist of either zinc borate or talc or both and optionally other ingredients. The compound achieves a UL 94 rating of V-0 or V-1 at 1.6 mm.
FLAME RETARDANT COMPOSITIONS, MASTERBATCHES, GLASS FIBER-NYLON COMPOSITIONS AND PREPARATION METHODS THEREOF
A flame retardant composition includes 40-60 parts by weight of phosphonate, 5-15 parts by weight of an organosilicon flame retardant, and 2-8 parts by weight of an inorganic silicon synergist. The phosphonate is prepared by a method including: (1) condensing a compound represented by formula (I) such that some of the compounds form a polymer, giving a partially condensed product; and (2) reacting a rare earth inorganic salt with the partially condensed product to form the phosphonate.
