Estimating the term…
The invention relates to a thermosensitive adhesive composition comprising: a) a first monomer chosen from the group of alkyl acrylates and alkyl methacrylates containing in the alkyl group 4 to 10 carbon atoms; b) a second monomer chosen from the group of alkyl acrylates or methacrylates containing in the alkyl group 1 to 3 carbon atoms, acrylamides, methacrylamides and other unsaturated monomers; and c) 1 to 15 mole % of acrylic acid, methacrylic acid and/or hydroxyethyl methacrylic acid, which copolymer has a glass transition temperature between 45 and 70° C.
A thermosensitive adhesive composition based on a copolymer comprising:
An adhesive composition according to any of the preceding claims, wherein the acrylic acid, methacrylic acid and/or hydroxyethyl methacrylic acid is present in an amount of 2 to 8 mole %.
An adhesive composition according to any of the preceding claims, wherein the first monomer is chosen from the group of n-butyl, n-pentyl, n-hexyl, isoheptyl, n-nonyl, n-decyl, isohexyl, 2-ethyloctyl, isooctyl and 2-ethylhexyl acrylates or methacrylates, and combinations thereof.
An adhesive composition according to any of the preceding claims, wherein the second monomer is chosen from the group of acrylamide, diacetone acrylamide, N-vinyl-2-pyrrolidone, vinyl acetate, N-isopropyl acrylamide, and methyl methacrylate, and combinations thereof.
An adhesive composition according to any of the preceding claims, wherein the copolymer has a weight average molecular weight of between 2000 and 25,000.
An adhesive composition according to any of the preceding claims in the form of an aqueous dispersion.
Use of an adhesive composition according to any of the preceding claims for adhering a prosthesis to human epithelium.
