    摘要： Solid burn-resistant polymeric compositions are formed by reacting substances such as Cl(PNCl2)9PCl4 and (PNCl2)3 4 with epoxy resins to form PNCl2-epoxy pre polymers. These prepolymers are blended with orgainc liquid prepolymers such as phenolics, epoxies, polyurethanes and polyesters and the blends are cured to form fire resistant plastics, wherein initial P,N, and Cl contents are wholly retained. Those two components, i.e., PNCl2 component and epoxy resin are admixed with liquid organic prepolymers (and polymerization catalysts therefor) and the system is then cured, usually by heating, whereby the PNCl2-epoxy polymer is formed in situ along with the matrix polymer, or in some cases chemically bonded to the organic polymeric crosslinked plastic.

    摘要翻译： 通过将物质如Cl（PNCl 2）9 PCl 4和（PNCl 2）3-4与环氧树脂反应形成固体耐燃聚合物组合物以形成PNCl 2 - 环氧预聚物。 这些预聚物与有机液体预聚物如酚醛树脂，环氧树脂，聚氨酯和聚酯共混，并将共混物固化形成耐火塑料，其中初始的P，N和Cl含量被完全保留。 将这两种组分，即PNCl 2组分和环氧树脂与液体有机预聚物（及其聚合催化剂）混合，然后通常通过加热固化体系，由此PNCI-环氧聚合物与基质聚合物一起原位形成， 或在某些情况下化学键合到有机聚合物交联塑料上。

    摘要： SOLID BURN-RESISTANT POLYMERIC COMPOSITIONS ARE FORMED BY REACTING SUBSTANCES SUCH AS C1(PNCL2)9PCL4 AND (PNCL2)3-4 WITH EPOXY RESINS TO FORM PNCL2-EPOXY PREPOLYMERS. THESE PREPOLYMERS ARE BLENDED WITH ORGANIC LIQUID PREPOLYMERS SUCH AS PHENOLICS, EPOXIES, POLYURETHANES AND POLYESTERS AND THE BLENDS ARE CURED TO FORM FIRE RESISTANT PLASTICS, WHEREIN INITIAL P, N, AND CL CONTENTS ARE WHOLLY RETAINED. THOSE TWO COMPONENTS, I.E., PNCL2 COMPONENT AND EPOXY RESIN ARE ADMIXED WITH LIQUID ORGANIC PREPOLYMERS (AND POLYMERIZATION CATALYSTS THEREFOR) AND THE SYSTEM IS THEN CURED, USUALLY BY HEATING, WHEREBY THE PNCL2-EPOXY POLYMER IS FORMED IN SITU ALONG WITH THE MATRIX POLYMER, OR IN SOME CASES CHEMICALLY BONDED TO THE ORGANIC POLYMERIC CROSS-LINKED PLASTIC.

    摘要： A FLOWABLE STABLE HIGH EXPANSION FOAM COMPOSITION BASED ON A UREA-FORMALDEHYDE RESIN IS PROVIDED HAVING GOOD STRENGHT PROPERTIES AND A RETARDED SETTING TIME. IN ADDITION A PROCESS OF FOAMING IS PROVIDED WHICH PRODUCES A HIGH STRENGTH, HIGH EXPANSION FOAM FROM A NUMBER OF FOAM SYSTEMS. THIS PROCESS ALSO ENABLES UMPROVED GENERATION AND TRANSPORT OF THE HIGH EXPANSION FOAMS THROUGH ENCLOSED AREAS BY INTERMITTENTLY FOAMING THE AQUEOUS PREFOAM COMPOSITION AND PASSING IT THROUGH AN ENCLOSED AREA.
