The compact battery in Apple \'s iPods relies on a polymer made by Kureha , which holds70 % of the market , and whose factory was damaged .

苹果的iPod小型电池依赖于日本吴羽（它占有70%的市场份额）的一种聚合物，其工厂也遭到破坏。

The PPS resin prepared under the optimum reaction condition ( 170 ~ 240 C , for 4-7hours ) was a white porous aggregate , and became light grey yellow when the product melt was cooled , the molecular weight of the product was 30000 ~ 50000 , between those of Kureha high-molecular PPS W-205 and W-214 ; the property of the product was similar to Kureha linear high-molecular Fortron PPS , characterized by low melt viscosity and less color distortion during processing .

在最佳反应条件下（反应温度170～240℃，反应时间4～7h）制得的PPS树脂呈白色疏松状聚集体，产品熔融冷却后呈浅灰黄色，分子量为3～5万，介于吴羽线型高分子量PPSW-205和W-214之间，树脂性能类似吴羽线型高分子量PPS树脂-FortronPPS，具有熔融粘度低、加工变色小等特点.
