Hydrophilic Polymers - Sigma-Aldrich

Hydrophilic polymers contain polar or charged functional groups, rendering them soluble in water. Within this section, most hydrophilic polymers are grouped by the chemistry of their structure. For example, acrylics include acrylic acid, acrylamide, and maleic anhydride polymers and copolymers.

Feb 06, 2008· For example, while ethanol (CH3CH2OH) is a hydrophilic molecule, using the PATTY method, the two carbon atoms of the ethyl group (CH3CH2-) and the oxygen atom of the hydroxy group (-OH) are assigned as being “hydrophobic” (ep6) and “polar” (ep5), respectively. VICI entries are defined in terms of ATOM entries.
