| Catalog Number |
ACMA00029362 |
| Structure |
 |
| Molecular Weight |
2.2*103 g/mol |
| Characterization |
The molecular weight and polydispersity index (PDI) of polyisobutylene are obtained by size exclusion chromatography. |
| Packaging |
0.5g, 1g, 2g, 5g |
| PDI |
Mw/Mn=1.35 |
| Purification |
After polymerization the catalyst residues are removed by filtration and washing with acidic water after which the pH is returned to nominal values and finally the polymer is freeze dried. |
| Synthesis Procedure |
Deuterated d8 Polyisobutylene is synthesized by living cationic polymerization of d4 isobutylene in hexane at -78 °C using a tin based catalyst and a 2,4,4-dimethyl pentene / HCl initiator. Monomer used was d8 isobutylene. |
