Abstract (en)

[origin: WO9945547A1] This invention utilizes syndiotactic styrene polymer to produce a thin film suitable for insulating electrically conductive metal support structures from current conducting magnet wire. The addition of impact modifiers enables the thin sheet to withstand the mechanical stress of fabrication in motor assembly operations. The resultant sheet exhibits good heat resistance, electrical dielectric strength and moisture insensitivity which provides greater dimensional stability and resistance to hydrolysis.
