I, wherein n is an integer in the range of from 1 to 29 and the carboxylic acid is acetic acid, acrylic acid or methacrylic acid.
Aldehydes RFCH2CHO (R(F) is a linear perfluoroalkyl chain) have been obtained in the addition reaction of R(F)I to vinyl acetate in the presence of zinc. RFCH2CHIOAc is formed as an intermediate in the course of the reaction. Under appropriate conditions, RFCH2CHO and its acylal or acetal derivatives are obtained in good yields.
The subject invention discloses curable polymeric N-halamine precursors which are useful for forming an antimicrobial surface coating on an object or article of manufacture. The present invention more specifically reveals a cross-linkable, water soluble polymer which is particularly useful for coating substrates and which can be activated to provide such substrates with antimicrobial and/or odor reducing characteristics, said cross-linkable polymer being comprised of amine, amide, or imide group containing repeat units and epoxide or methylol group containing repeat units, wherein the ratio of amine, amide or imide group containing repeat units to epoxide or methylol group containing repeat units is at least 2:1.
