Abstract
The invention relates to a polymer or oligomer comprising a) An oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, and b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via c) a linking moiety comprising i) a urethane group and ii) a group selected from urethane group, urea group, and biuret group.
Claims11
A polymer or oligomer comprising
- a) an oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, the core comprising one or more of a polymer or oligomer of ethyleneimine, a polymer or oligomer of a trialkanol amine, a branched polyester, and a polyamide, and
- b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via
- c) a linking moiety comprising i) a urethane group and ii) one or more of a urethane group, a urea group, and a biuret group.
A process of preparing a polymer or oligomer, comprising the steps of
- i) reacting a mono-alcohol having a hydrocarbyl group having 12 to 100 carbon atoms with a diisocyanate to provide an intermediate having one isocyanate group, one urethane group, and one hydrocarbyl group having 12 to 100 carbon atoms,
- ii) providing an oligomeric or polymeric core comprising one or more of a polymer or oligomer of ethyleneimine, a polymer or oligomer of a trialkanol amine, a branched polyester, and a polyamide,
- iii) reacting the intermediate prepared in step i) with the oligomeric or polymeric core provided in step ii);
- the resulting polymer or oligomer comprising:
- a) an oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, and
- b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via
- c) a linking moiety comprising i) a urethane group and ii) one or more of a urethane group, a urea group, and a biuret group.
A process of preparing a polymer or oligomer, comprising the steps of
- i) reacting a mono-alcohol having a hydrocarbyl group having 12 to 100 carbon atoms with a mono- or diisocyanate having a uretdione group to provide an intermediate having a uretdione group, one or two urethane groups, and one or two hydrocarbyl groups having 12 to 100 carbon atoms,
- ii) providing an oligomeric or polymeric core comprising one or more of a polymer or oligomer of ethyleneimine, a polymer or oligomer of a trialkanol amine, a branched polyester, and a polyamide,
- iii) reacting the intermediate prepared in step i) with the oligomeric or polymeric core provided in step ii);
- the resulting polymer or oligomer comprising:
- a) an oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, and
- b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via
- c) a linking moiety comprising a urethane group and a biuret group.
