Reactions between hexachlorocyclotriphosphazene and hexamethylcyclotrisiloxane: polymerization, ring cleavage, and crosslinking
TL;DR: In this paper, two phenomenés: equilibre cycle phosphore-cycle siloxane, homopolymerisation of (NPCl 2 ) 3 en haut polymere and clivage du squelette siloxANE by les liaisons P-Cl donnant des phosphazenes cycliques avec un ou deux groupes lateraux ω-chlorosiloxane.

Colored polymers comprising poly(organophosphazenes) with chromophores as substituent groups
TL;DR: In this article, the authors present a method of preparation for poly(organophosphazenes) with chromphoric substituents and use it to add color to polyphosphazene polymers to produce food colorants, colored films, colored fibers and similar products.
Book ChapterDOI
Phosphazene High Polymers
TL;DR: In this article, the incorporation of inorganic elements into a polymer structure should broaden the range of properties accessible in polymeric substances, and many elements other than carbon could form part of a macromolecular backbone.
Journal ArticleDOI
Phase changes of poly(alkoxyphosphazenes), and their behavior in the presence of oligoisobutylene
TL;DR: A series of closely related polyphosphazenes with propoxy, pentoxy, hexoxy, octoxy, isostearyloxy, and 2-(2-methoxyethoxy)ethoxy (MEE) side groups, together with cosubstituent species with both the alkoxy and MEE side chains, were studied for their morphology and miscibility with oligoisobutylene (OIB) as mentioned in this paper.
Journal ArticleDOI
Hydroxyapatite–Polyphosphazane Composites Prepared at Low Temperatures
TL;DR: In this paper, the characteristics of composites comprising HAp and a biomedical polymer and prepared at low temperatures are described, and the kinetics of HAp formation in the presence of a polyphosphazene polymer that carries carboxylic acid moieties (acid-PCPP) were established at temperatures from 25° to 50°C.
