Abstract: The invention relates to a new and improved process for making an epoxidized olefin, specifically, polyisobutylene epoxide. The inventive process generally comprises (a) combining a polyisobutylene and a solvent to form a first mixture, (b) combining a peroxide, a carboxylic acid and an acid catalyst to form a second mixture, (c) reacting the first and second mixtures forming a non-aqueous phase comprising a polyisobutylene epoxide and an aqueous phase; (d) separating the non-aqueous phase from the aqueous phase; (d) washing and neutralizing the non-aqueous phase, and (e) recovering in a high yield and high purity polyisobutylene epoxide. It was discovered that specific mole ratios and amounts of reactants provide for recovering in high yield and purity polyisobutylene epoxide with reduced detrimental by-products.

Abstract: The invention relates to a bis-polyisobutylene alcohol amine compound and compositions thereof. The invention also is directed to a new process for making the bis-polyisobutylene alcohol amine by reacting a polyisobutylene epoxide with a polyamine, optionally in the presence of a catalyst, a protic solvent initiator and/or a diluent. In addition, the invention further relates to the many uses of the bis-polyisobutylene alcohol amine including but not limited to its use in lubricants, surfactants, emulsifiers, resins, and the like.

Abstract: A method of making a low-fluoride reactive PIB composition includes (a) providing a modified C4 feedstock by way of blending a mixed C4 feedstock with a second feedstock having a lower LB/IsoB ratio; or providing a C4 feedstock with an LB/IsoB index of less than 10%; (b) feeding the modified C4 feedstock or the C4 feedstock with an LB/IsoB index of less than 10% to a CSTR with a homogeneous catalyst comprising BF3 and a modifier selected from alcohols, ethers and mixtures thereof; (c) polymerizing the modified C4 feedstock or the C4 feedstock with an LB/IsoB index of less than 10% in the reactor while maintaining the reactor at a temperature above ?15° C. and utilizing a residence time less than 45 minutes to produce a crude PIB composition in a polymerization mixture; and (d) recovering a purified PIB composition from the polymerization mixture having a molecular weight, Mn, from 250 to 5000 Daltons and an alpha vinylidene content of at least 50 mol %.
