我国聚氨酯(PU)制品的产量预计2002年达到950kt,2005年将达到1 070 kt。随着聚氨酯的迅速发展,我国生产聚氨酯的原料聚醚多元醇的需求也逐年增长。 聚醚多元醇可归纳为三种类型:一种是以多元醇或有机胺为起始剂与环氧丙烷(PO)或环氧丙烷(PO)和环氧乙烷(EO)的聚合物,通称为PPG,这种产品在PU中用量最大。另一种是聚合物多元醇,它以PPG为基础,然后用
China’s production of polyurethane (PU) products is expected to reach 950kt in 2002 and to reach 1 070kt in 2005. With the rapid development of polyurethane, the demand for polyether polyols, the raw material for polyurethane production in our country, also increases year by year. Polyether polyols can be grouped into three types: one is a polymer based on polyols or organic amines as initiator with propylene oxide (PO) or propylene oxide (PO) and ethylene oxide (EO) Commonly known as PPG, this product is the most used in PU. The other is a polymer polyol, which is based on PPG and then used
