“…The incorporation of organophosphorus functionality, either within the parent chain or as groups appended to it, has led to the production of inherently fire‐retardant polymers. Several systems have been reported on poly(arylene ether)s, polyimides, polyamides, polyesters, and bismaleimide and epoxy networks 14–39. Recently, Wang and coworkers31–39 reported several P‐containing polymer systems based on (6‐oxido‐6H‐ dibenz〈 c,e 〉〈1,2〉oxaphosphorin‐6‐yl)hydroquinone (DOPOHQ), a P‐diol derived from the addition reaction of 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene 10‐oxide (DOPO) to p ‐benzoquinone.…”

Two series of phosphorus-containing aromatic poly(ester amide)s with inherent viscosities of 0.46 -3.20 dL/g were prepared by low-temperature solution polycondensation from 1,4-bis(3-aminobenzoyloxy)-2-(6-oxido-6H-dibenz͗c,e͗͘1,2͘oxaphosphorin-6-yl)naphthalene and 1,4-bis(4-aminobenzoyloxy)-2-(6-oxido-6H-dibenz͗c,e͗͘1,2͘oxaphosphorin-6-yl)naphthalene with various aromatic diacid chlorides. All the poly(ester amide)s were amorphous and readily soluble in many organic solvents, such as N, N-dimethylformamide, N,N-dimethylacetamide (DMAc), and N-methyl-2-pyrrolidone (NMP). Transparent, tough, and flexible films of these polymers were cast from DMAc and NMP solutions. Their casting films had tensile strengths of 71-214 MPa, elongations to break of 5-10%, and initial moduli of 2.3-6.0 GPa. These poly(ester amide)s had glass-transition temperatures of 209 -239°C (m-series) and 222-267°C (p-series). The degradation temperatures at 10% weight loss in nitrogen for these polymers ranged from 462 to 489°C, and the char yields at 800°C were 55-63%. Most of the poly(ester amide)s also showed a high char yield of 35-45%, even at 800°C under a flow of air. The limited oxygen indices of these poly(ester amide)s were 35-46.

“…Razvoj postupaka sinteze hibridnih materijala je svakako izazov za naučnike i postaje predmet izučavanja industrijske i akademske javnosti. Istraživanje na hibridnim materijalima s polimernom matricom počelo je 1985. godine radom Wen I Wilkesove grupe [28][29][30][31][32][33] na modifikaciji poli(dimetilsiloksana) (PDMS), (-Si(CH3)2O-)n, jer se pretpostavilo da će sličnost građe njegovog glavnog Si-O-Si lanca sa SiO2 gelom olakšati povezivanje dveju faza. Time se postiglo uporedno punjenje i "vulka-nizacija", tj.…”

“…The first method is more preferable for highperformance polymers. [24][25][26][27][28] In this work, the synthesis of new PUIs having higher thermal stability and higher flame resistance was aimed. The synthesis was designed as first the preparation of diacyl azide-containing bisimide part, which has phosphorus atom and then its conversion to diisocyanate via Curtius rearrangement.…”

The preparation of new poly(urethaneimide)s (PUIs) having acceptable thermal stability and higher flame resistance was aimed. Two new aromatic diisocyanate-containing methyldiphenylphosphine oxide and triphenylphosphine oxide moieties were synthesized via Curtius rearrangement in situ and polymerized by various prepared diols. Four aliphatic hydroxy terminated aromatic based diols were synthesized by the reaction between ethylene carbonate and various diphenolic substances. Chemical structures of monomers and polymers were characterized by FTIR, 1 H NMR, 13 C NMR, and 31 P NMR spectroscopy. Thermal stabilities and decomposition behaviors of the PUIs were tested by DSC and TGA. Thermal measurements indicate that the polymers have high thermal stability and produce high char. Polymers exhibit quite high fire resistance, evaluated by fire test UL-94. The films of the polymers were prepared by casting the solution. Inherent viscosities, solubilities, and water absorbtion behaviors of the polymers were reported in. V
