Hello All,
I want to conduct some experiments with high molecular weights PVPh, however the available molecular weights on Scientific Polymer Products, Polymer Source. Inc. and any other such website are only Mw = 11,000 and Mw = 22,000 g/mol.
It would be really helpful if anybody could provide any information related to the same.
Thank you in advance.
Dear Tulika Sharma, better to specify the targetted MW. In the following documents, higher MWs are used. In addition to that, it is also possible to obtain even higher MWs by post-polymerization modification of polystyrene, a polymer easy to polymerize either by conventional addition techniques or by the living/controlled polymerization ones. Please have a look at the following documents. My Regards

Dear Abdelkader Bouaziz,
Thank you very much for your response. I will check the links provided by you.
I need PVPh with a molecular weight greater than 800,000 g/mol.
Regards
No thanks, I don't think it is possible to find MW higher than 100,000g/mol. Try to modify polystyrene, it is possible to go ever beyond the one you need. Best of Luck
Hi Tulika,
You may make an inquiry at Alfa Chemistry, they offer kinds of good-quality materials.
