Abstract
Organic polymer surfaces are modified by contacting such surfaces with a halohydroxy compound and a cationic compound of an acid having a pK.sub.a >2.5. Preferably the organic polymer is selected from the group consisting of polyesters, aromatic polyamides, polyimides, and graphitic polymers and the contacting is conducted at an elevated temperature.
Claims10
A solid organic polymer containing on its surface a reaction product of a halohydroxy organic compound having primary halogen and hydroxyl functionalities, and a halohydrin value of less than or equal to 1.7% and an epoxy value of less than or equal to 0.36% and a cationic compound of an acid having a pK.sub.a >2.5.
The organic polymer of claim 6 wherein said halohydroxy organic compound is selected from the group consisting of oxy-w-dichloroalkylenes, w-trichloroalkylenes, thiochloropropylenes, oxychlorobutylenes, oxychloropropyl compounds, oxychloroalkyl compounds, polyoxychloropropylene polycarboxylic esters, and polythiochloropropylenes.
