For some time Innovative Science Corporation has been involved in basic R&D on new systems for the green polymerization of isobutene (IB).\u00a0 This series of projects (conducted under contract) have yielded a number of interesting and valuable methodologies for the polymerization of IB where benefits include lower energy consumption, high yields, and no toxic solvents required.\u00a0 In this blog we announce (publically) the details of one such system.<\/p>\n
It has been discovered that scandium(III) triflate is capable of inducing polymerization of IB to both low and high MW grades of PIBs in neat monomer (and in aliphatic media) in conjunction with a number of initiator subsets (e.g. halogens, Br\u00f6nsted acids, alcohols, ethers, nitroalkanes, and water {just to name a few}).\u00a0 Depending on the identity of the initiator, products with high MWs can be obtained at elevated reaction temperatures.\u00a0 For example, in one experiment reaction at 0 \u00b0C led to the production of PIB with Mw<\/sub> = 250 kg\/mol (in limited yield).\u00a0 In many instances, low MW grades of PIBs with high exo-olefinic end group contents (ca. 80-90 %) can be produced in high yields at room temperature.\u00a0 Moreover, studies have indicated that the coinitator is itself recyclable and retains is activity upon reuse.<\/p>\n More specific details concerning this research will be disseminated in the peer-reviewed literature.\u00a0 For those who have interest in owning US patent rights please contact our president, Dr. S.P. Lewis.\u00a0 Release date 6\/21\/12<\/p>\n","protected":false},"excerpt":{"rendered":" For some time Innovative Science Corporation has been involved in basic R&D on new systems for the green polymerization of isobutene (IB).\u00a0 This series of projects (conducted under contract) have yielded a number of interesting and valuable methodologies for the … Continue reading
