Ronald L. Dieck - Lancaster PA
Edwin J. Quinn - Lancaster PA

Assignee:

Armstrong Cork Company - Lancaster PA

International Classification:

C08L 4302

US Classification:

260824R

Abstract:

This invention relates to blends of polyphosphazenes and silicone polymers. The blends of this invention can be formed into coatings, sheets or films or into flexible or semi-rigid foams. The blends are extremely fire retardant and produce low smoke loads, or essentially no smoke, when heated in an open flame.

International Classification:

C08J 906

US Classification:

260 25R

Abstract:

Poly(aryloxyphosphazene) copolymers and foams thereof having a significant portion of C. sub. 1 - C. sub. 4 alkoxyphenoxy groups are described. The copolymers consist of the units which occur in a nonregular fashion and are represented by the following general formulas: ##STR1## wherein R. sub. 1 represents a C. sub. 1 - C. sub. 4 linear or branched alkyl radical in the ortho-, meta-, or para-position, and R. sub. 2 represents hydrogen, a C. sub. 1 - C. sub. 10 linear or branched alkyl radical, or a C. sub. 1 - C. sub. 4 linear or branched alkoxy radical substituted on any sterically permissible position on the phenoxy group, with the proviso that when R. sub. 2 is alkoxy, OR. sub. 1 and R. sub. 2 are different. The copolymers of this invention may contain small amounts of randomly distributed units in addition to the repeating units described above, these additional units containing reactive sites enabling the properties of the copolymers to be modified by crosslinking and/or curing.

International Classification:

C08G 7904
C08J 910

US Classification:

521 95

Abstract:

Polymers comprising randomly repeating units of the general formula ##STR1## wherein R. sub. 1 is linear or branched C. sub. 1 -C. sub. 10 alkoxy, R. sub. 2 is linear or branched C. sub. 1 -C. sub. 10 alkyl, hydrogen or halogen, and W is C. sub. 2 to C. sub. 10 alkenyl-substituted aryloxy. These novel polymers are elastomers and may be used to form flexible and semirigid foams and coatings. They display good fire retardance and low smoke levels.

International Classification:

B32B 300

US Classification:

428 57

Abstract:

Vinyl heat welding rod for seam sealing vinyl resilient flooring, whether in sheet or tile form, are used to obtain a homogeneous, monolithic appearing surface. This rod is specifically made to duplicate the appearance of the flooring material. For a chip-image flooring structure, a sheet of multicolored chips having a similar, but different formulation from that of the flooring material is prepared and the sheet is cut into suitable strips, heat pressed in a rod mold, end adhered or further molded to form the desired length, and used as a vinyl heat welding rod for sealing seams in flooring. Thus, the chip pattern is evident in the seam area and does not appear different when compared to the adjacent surface.

Abstract:

Poly(aryloxyphosphazene) polymers and foams thereof having di(C. sub. 1 -C. sub. 10)alkylaminophenoxy groups are described. The polymers consist of the units which occur in a nonregular fashion and are represented by the following general formula: ##STR1## wherein R. sub. 1 and R. sub. 2 are the same or different and are C. sub. 1 -C. sub. 10 linear or branched alkyl radical. Copolymeric dialkylaminoaryloxy-aryloxyphosphazenes are disclosed represented by units of the general formula: ##STR2## wherein R. sub. 1 and R. sub. 2 are defined above and R represents hydrogen, halogen, C. sub. 1 -C. sub. 10 linear or branched alkyl radical, or C. sub. 1 -C. sub. 4 linear or branched alkoxy radical substituted on any sterically permissible position on the other phenoxy group. The radical NR. sub. 1 R. sub. 2 is substituted in the meta or para position on the phenoxy radical.
