EO-PO copolymer--help needed
Thread Content
What is the maximum molecular weight that can be achieved for the series of EO-PO copolymer products, and which are the main manufacturers in China? Thank you so much! It’s needed for experiments, so I had to find a local agent in China for a Canadian company; 1 gram costs around 300 dollars, and the boss refused to buy it. . . The molecular weights of the others are all too low. . I searched for over ten days and made numerous calls. . . . I would like to seek advice from experts here. . . . No gratitude remains. . .
The general molecular weight is around 3000! There are so many in the country! Liaoning Jinhua, Takahashi Petrochemical, Nanjing Zhongshan, Hongbaoli, Koria, Suzhou Sinochem, and so on!
