Abstract: A B S T R A C T Poly(haloaryloxyphosphazenes) which consist of recurring units represented by the following general formula   in which n is between 20 and 50,000 and R1, R2 and R3 are monovalent radicals selected from the group consisting of H, Cl, Br, and alkyl (one to five carbon atoms) and at least one R group is halogen, the improvement which comprises the formation of the polymer by reaction of poly(dichloro-phosphazene) with a stoichiometric excess of alkali metal salt of a phenol substituted in at least one of the meta or para positions at a temperature and length of time between about 115°C for 100 hours and about 160°C for about 5 hours, whereby a poly(haloaryloxyphosphazene) product free from P-Cl sites and soluble in tetrahydrofuran is obtained.  The polymers of this invention are film formers, which often can be rendered into fibers.  Many of these poly(aryloxyphosphazenes) are particularly useful in flame-retardant appli-cations in the form of wire insulation, structural composites, carpet backing and in wearing apparel.  Because the homopolymers of this invention are free of P-Cl sites (i.e. less than 0.1% chlorine at P-Cl), the polymers may be safely utilized in moist environments.

Abstract: A B S T R A C T      A protective gaiter which extends from a wearer's instep to just below his knee.  A portion of the gaiter forms completely closed pocket which contains an energy-absorbing pad.  The pocket and the pad are both elon-gated, covering substantially the length of the gaiter, and include a concave-ly shaped bottom edge which lets the gaiter be conveniently positioned around the wearer's instep so that it fits over and protects the wearer's shinbones, as well as covering many of the major bones and muscles of the wearer's leg. In the manufacture of the protective gaiter, identical front and linear panels and a somewhat smaller, interposed back panel are aligned and sewn together along one longitudinal edge.  An elastic strip, which forms the stirrup of the protective gaiter, is next secured between opposing ends of the bottom edges of the front and liner panels, which bottom edges are then sewn to-gether.  The outer longitudinal edges of the front, liner and back panels are then aligned and sewn together.  An energy-absorbing protective pad is then inserted into the pocket defined by the front and liner panels, and the upper edges thereof thereafter sewn together.  A collar secured to the upper edge of the gaiter completes the article.
