Abstract: The present invention relates to electrostatic dissipative polymeric compositions comprising a polyether polyurethane which can be blended with one or more base polymers. In some applications, the polyurethane is useful without further blending. Further, the polyurethane blends can be blended with glass beads or glass fibers which have a synergist effect when combined with the electrostatic dissipative agent.

Abstract: The present invention relates to electrostatic dissipative polymeric compositions comprising an effective amount of a chain extended polymer and a matrix polymer or matrix polymer blend. The chain extended polymer of the subject invention has electrostatic dissipative properties and is formed from low molecular weight polyethers which are reacted with a chain extender to furnish a useful additive.

Abstract: The present invention relates to electrostatic dissipative impact modified polymeric compositions comprising an effective amount of a chain extended block copolymer, polyvinyl halide and no more than 10 weight parts of a polymeric impact modifier per 100 weight parts of polyvinyl chloride. The chain extended block copolymer is formed from reacting a di-functional polyether with a chain extender which is a condensate selected from the group consisting of polyundecanolactam, polydodecanolactam, poly(11-aminoundecanoic acid) and (12-aminododecanoic acid).

Abstract: A thermoplastic polyurethane is provided which has electrostatic dissipative properties. The thermoplastic polyurethane comprises the polymeric reaction product of an ethylene ether oligomer glycol intermediate co-reacted with a non-hindered diisocyanate and an extender glycol to produce the polyurethane polymer. The ethylene ether oligomer glycol intermediate comprises a polyethylene glycol. The oligomer glycol intermediate has an average molecular weight from about 500 to about 5,000.

Abstract: A method of manufacturing an electrostatic dissipating material (and compositions derived therefrom), wherein the method relates to:heat mixing or blending a first, a second and a third component in two steps, whereby in the first step the second and third components are first heat mixed or blended together to provide an initial mixture, and in a second step the first component is heat mixed or blended with said initial mixture,the first component is a polyolefinic, urethane, condensation, vinylic or styrenic polymer, the second component is a oxirane copolymer, and the third component is a polymer additive.

Abstract: A nine-membered ring phosphonate compound having the formula ##STR1## wherein R.sup.1 is hydrogen or methyl, R.sup.2 is phenyl or substituted phenyl wherein the substitution is one or more of halogen, nitro, lower alkyl, cyclohexyl, alkoxy, naphthoxy or phenoxy and R.sup.3 and R.sup.4 are the same or different and are lower alkyl of up to eight carbon atoms, preferably methyl, is formed by the reaction of acrylic or methacrylic acid with a compound of the general formula ##STR2## wherein R.sup.2, R.sup.3 and R.sup.4 are as above. The ring phosphonates are useful for forming flame-retardant compositions from mixtures comprising the phosphonate and methyl methacrylate.

Abstract: A thermally stable flame-resistant phosphonate polymer of the structure ##STR1## WHEREIN R.sup.1 is methyl or ethyl, R.sup.2 is hydrogen or methyl and n is 3 to 100, is formed by the reaction of acrylic or methacrylic acid with an alkyl bicyclic phosphite of the structure ##STR2## wherein R.sup.1 is as above. The phosphonate polymer is useful in forming flame-resistant acrylic compositions such as molding powders and sheets from mixtures comprising the polymer and methyl methacrylate.This is a division, of application Ser. No. 139,948 filed May 3, 1971, now U.S. Pat. No. 3,755,270.
