    • This invention is an antistatic thermoplastic, phase-segregated polyurethane containing, as an antistatic additive an effective amount of a monovalent metal tetraphenylboron salt, in the substantial absence of a fatty acid salt, a C.sub.6 -C.sub.30 carboxylic acid ester or phosphate ester compound.Suprisingly, it has been found that, with this particular type of polyurethane, tetraphenylboron salts are very effective antistatic additives even in the absence of enhancer compounds as were previously employed. Accordingly, the antistatic polyurethane is useful for applications such as electronics components and packaging, and other applications where static dissipative ability is needed or desirable.
    • 本发明是一种抗静电热塑性相分离聚氨酯,其在基本不存在脂肪酸盐,C6-C30羧酸酯或磷酸酯化合物的情况下,含有有效量的一价金属四苯基硼酸盐作为抗静电添加剂。 令人惊讶的是,已经发现,对于这种特定类型的聚氨酯,四苯基硼酸盐即使在不存在增强剂化合物的情况下也是非常有效的抗静电添加剂。 因此,抗静电聚氨酯可用于诸如电子部件和包装之类的应用,以及需要静电耗散能力的其它应用。
