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.

Chain extended low molecular weight polyoxiranes and electrostatic

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.

Chain extended low molecular weight polyoxiranes for electrostatic

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). The compounds further comprise a heat distortion modifier which does not interfere with ESD properties and is selected from the group consisting of styrene-acrylonitrile copolymer, alpha methyl styrene-styrene-acrylonitrile terpolymer, a polymer of alpha methyl styrene-styrene-N-cyclohexyl maleimide, N-phenylmaleimide, imidized polymethyl methacrylate, post-chlorinated polyvinyl chloride, styrene-maleic anhydride polymer, imidized styrene-maleic anhydride polymer, acrylic-imide copolymer, acrylonitrile-methylmethacrylate copolymer, acrylonitrile-acrylate-polybutadiene graft copolymer, alpha methyl styrene-methylmethacrylate-acrylonitrile terpolymer, alpha-methyl styrene-styrene-methylmethacrylate terpolymer, alpha methyl styrene-methylmethacrylate copolymer, alpha methyl styrene-acrylonitrile copolymer, alpha methyl styrene-methylmethacrylate graft copolymer on polyacrylate rubber, polycarbonate, and brominated polycarbonate.

Electrostatic dissipative blends of PVC, polyetheramides and an impact

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.

Polyurethane for use in electrostatic dissipating applications

A hinged flexible article is provided which has rigid or semirigid substrate means with an insert of a hinge material which permits repeated flexing of the article about the hinge without failure. The substrate means has a hardness of at least about 35 Shore D as measured by ASTM test D-2240, while the hinge material has a hardness of from about 25 to about 60 Shore D as measured by ASTM test D-2240.

Hinged rigid or semirigid product
