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.
Claims66
A bis-polyisobutylene alcohol amine compound(s) comprising the following general formula:
- wherein x is an integer from 1 to about 200, R is a C1-C10 branched, cyclic or straight chained alkylene group, and y is an integer between 1 to about 20.
A bis-polyisobutylene alcohol amine composition, the composition comprising a bis-polyisobutylene alcohol amine compound(s) further comprising the following general formula:
- wherein x is an integer from 1 to about 200, R is a C1-C10 branched, cyclic or straight chained alkylene group, and y is an integer between 1 to about 20.
A bis-polyisobutylene alcohol amine composition comprising:
- (i) 5 mol % to 98 mol % of one or more bis-polyisobutylene alcohol amine compound(s), (ii) up to 15 mol % of unreacted polyisobutylene, and (iii) up to 15 mol % of one or more unreacted polyisobutylene epoxide, wherein the sum of the mol % of i, ii and iii together add to between 98 mol % and 100 mol %.
A bis-polyisobutylene alcohol amine compound.
A bis-polyisobutylene alcohol amine compound produced by the process comprising the step of:
- contacting in a reactor under reaction conditions a polyisobutylene epoxide and a polyamine in a mole ratio of polyamine to polyisobutylene epoxide of less than 0.9:1.
A process for making a bis-polyisobutylene alcohol amine composition, the process comprising the steps of:
- (i) contacting a polyisobutylene epoxide with a polyamine in the presence of a diluent forming a reaction mixture;
- and (ii) introducing a catalyst and a protic solvent initiator to the reaction mixture, wherein the mole ratio of polyamine to polyisobutylene epoxide is less than 0.7:1.
A lubricating composition comprising a bis-polyisobutylene alcohol amine compound(s) and/or composition.
A lubricating composition comprising a base oil and a bis-polyisobutylene alcohol amine composition.
