초록

A method of modifying the overall hydrophilic or hydrophobic nature of a high molecular weight free radical addition interpolymer, which is an azlactone-functional interpolymer, with a hydrophilic or hydrophobic nucleophilic compound is disclosed. Only the surface of the interpolymer can by hydrophilized or hydrophobized, as when the interpolymer is a coating, or the modification can take place throughout the entire bulk of the interpolymer.

청구항

1. A method for preparing thermoplastic, processable, hydrophilic- or hydrophobic-modified polymers comprising the steps: (a) interpolymerizing at a temperature in the range of room temperature to 100° C. in the presence of an amount of free radical initiator in the range of 0.01 to 5.0 weight percent (1) 1 to 50 mole percent of an alkenyl azlactone monomer, (2) 50 to 99 mole percent of at least one free radical addition polymerizable monomer, to form an interpolymer, said monomer being selected from the group consisting of vinyl aromatic compounds...
