Abstract
The present application discloses an adhesive composition comprising a polymer of the formulae A, B and C: and methods for using the adhesive composition. wherein x and y define the block polymer and are integer greater than 1.
Claims3
A method for sealing a first object having a surface to a second object having surface, the method comprising:
- 1) applying an adhesive to the surface of the first object;
- 2) contacting the surface of the first object comprising the adhesive with the surface of the second object for a sufficient period of time until the first and second object forms a seal;
- wherein the adhesive is an adhesive composition comprising a polymer of the formula A or B:
- wherein:
- each m and n is independently 100 to 1,000,000;
- each a, b, s and t is independently 0, 1 or 2;
- each L1, L2, L3 and L4 is independently absent or is independently selected from —CH2—, —O—, —S—, —(CH2)1-2—, —CH(CH2-)2, —C(O)O—, —C(O)OCH2—, —CH2C(O)O—, —CH2C(O)NH—, —C(O)NHCH2—, —C(O)NH— and —NR′— where R′ is selected from H, —CH3, —CH2CH3 and —CH2C6H5 or substituted benzyl, or a bond;
- each A, B, M and N is independently absent or is independently selected from the group consisting of an aryl, substituted aryl, heteroaryl, substituted heteroaryl, heteroarylammonium X− and substituted heteroarylammonium X−, wherein each X− is independently a counter anion selected from the group consisting of Cl−, Br−, I−, —SO4−2 and —PO4−3;
- provided that not all of L1, L2, L3 and L4 and A, B, M and N are absent;
- wherein the first object is dermis and the second object is selected from the group consisting of a metal, a metal oxide, a mineral, mica, silicon, glass, calcium, enamel, bone, steel, tooth enamel, tooth dentin, hydroxylapatite, kaolin and zirconia.
