Title: Salt-modified electrostatic dissipative polymers
IPC: C08L67/00
Filed: 1999-09-16
Abstract: A low molecular weight polyether oligomer is modified with a salt during chain extending reaction of the polyether oligomer to form electrostatic dissipative polymer products such as polyurethanes, polyether amide block copolymers and polyether-ester block copolymers. The reaction product polymers exhibit relatively low surface and volume resistivities, and static decay times which are not too fast or too slow, yet are free of excessive amounts of extractable anions, particularly chlorine, nitrate, phosphate and sulfate. The electrostatic dissipative polymers can be blended with a variety of base polymers to form plastic alloys, which in turn can be utilized to form articles useful in the manufacture of electrostatic sensitive electronic devices.
