介紹:
PPS的生產(chǎn)格局是:只有美國、日本和中國掌握PPS樹脂的工業(yè)化生產(chǎn)制造技術,擁有生產(chǎn)能力和產(chǎn)品。俄羅斯、印度正在積極進行PPS樹脂工業(yè)化生產(chǎn)的研發(fā)。美國雪佛龍菲利普斯公司和大日本油墨化學工業(yè)公司是全球主要的兩大大PPS樹脂生產(chǎn)商。
PPS新興的樹脂生產(chǎn)商和產(chǎn)品中,以日本吳羽化學工業(yè)公司和其推出的Fortron PPS——第二代線性高分子量PPS樹脂(其復合改性料由日本寶理公司生產(chǎn)、銷售)的發(fā)展引人注目。該樹脂生產(chǎn)工藝先進,產(chǎn)品質(zhì)量好,性能優(yōu),特別是它全面改善了PPS耐沖擊性能差、性脆的致命缺點。

"But he is not the only one thinking in this way, which means that production as a whole is continually being made more effective. Factories become bigger and bigger, and are gradually concentrated in fewer and fewer hands. What happens then, Sophie-"
"Er. . ."
"Fewer and fewer workers are required, which means there are more and more unemployed. There are therefore increasing social problems, and crises such as these are a signal that capitalism is marching toward its own destruction. But capitalism has a number of other self-destructive elements. Whenever profit has to be tied up in the means of production without leaving a big enough surplus to keep production going at competitive prices . . ."
