Abstract
There is provided an aqueous dispersible polymer composition comprising: (i) a hydroxyl functional dendritic polymer; (ii) one or more polar compounds, the polar compounds being miscible with both the hydroxyl functional dendritic polymer and an aqueous solvent; and wherein the one or more polar compounds are present in an amount sufficient to disperse the hydroxyl functional dendritic polymer in the aqueous solvent. There is also provided a coating composition comprising the same and processes for preparing the aqueous dispersible polymer composition and the coating composition.
Claims22
An aqueous dispersible polymer composition consisting essentially of:
- (i) a hydroxyl functional dendritic polymer, wherein the hydroxyl functional dendritic polymer is completely unmodified;
- and
- (ii) one or more polar compounds comprising one or more polar functional groups selected from the groups consisting of:
- hydroxyl functional group, amino functional group, halogen functional group, carbonyl functional group and carboxyl functional group, said polar compounds being miscible with both said hydroxyl functional dendritic polymer and an aqueous solvent;
- and wherein the weight ratio of said hydroxyl functional dendritic polymer to said polar compounds is from about 1:9 to about 4:1.
A coating composition comprising a first component and second component, wherein said first component consists essentially of:
- (i) at least one hydroxyl functional dendritic polymer, wherein the hydroxyl functional dendritic polymer is completely unmodified;
- (ii) one or more polar compounds comprising one or more polar functional groups selected from the groups consisting of:
- hydroxyl functional group, amino functional group, halogen functional group, carbonyl functional group and carboxyl functional group, said polar compounds being miscible with both said hydroxyl functional dendritic polymer and an aqueous solvent;
- (iii) an aqueous solvent;
- and
- said second component comprising:
- (iv) one or more cross-linkers;
- and
- wherein said first and second components, when mixed together, form the coating composition,
- wherein the weight ratio of said hydroxyl functional dendritic polymer to said polar compounds is from about 1:9 to about 4:1.
A process for preparing an aqueous dispersible polymer composition, said process comprising the steps of
- (a) mixing a hydroxyl functional dendritic polymer, one or more polar compounds in an aqueous solvent to form said aqueous dispersible polymer composition, said one or more polar compounds being selected to be miscible with both said hydroxyl functional dendritic polymer and said aqueous solvent;
- wherein the hydroxyl functional dendritic polymer is completely unmodified, wherein said one or more polar compounds comprise one or more polar functional groups selected from the groups consisting of:
- hydroxyl functional group, amino functional group, halogen functional group, carbonyl functional group and carboxyl functional group, and wherein the weight ratio of said hydroxyl functional dendritic polymer to said polar compounds is from about 1:9 to about 4:1.
