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 .
