This invention relates to polymers having enhanced hydrophilicity and thermal regulative properties. Exemplary polymers include aliphatic polyamide polymers and polyester polymers. The polymer has bonded thereto a hydrophilic polysiloxane having an affinity for the polymer and having a molecular weight greater than about 1000 g/mol preferably greater than about 2000 g/mol, and preferably greater than about 4000 g/mol. The polymer has substantially no polymerization with the hydrophilic polysiloxane. Alternatively, an aliphatic polyamide polymer is provided having enhanced hydrophilicity and thermal regulative properties. The polymer has bonded thereto an anionic hydrophilic polysiloxane having an affinity for the aliphatic polyamide polymer. The aliphatic polyamide polymer has substantially no polymerization with the anionic hydrophilic siloxane.
An aliphatic polyamide or polyester polymer having enhanced hydrophilicity and thermal regularitive properties, said polymer having bonded thereto a hydrophilic anionic polysiloxane polymer having a molecular weight greater than about 1000 g/mol and having an affinity for said polymer, said polymer having substantially no polymerization with the hydrophilic anionic polysiloxane polymer, said hydrophilic polysiloxane anionic polymer having the formula ##STR3## wherein X is selected from the group consisting of phosphate, phosphonate, phosphorylate, sulfonate, sulfate, sulfone and carboxylate groups;
The process of treating a polymer to impart hydrophilicity and thermal regulative properties thereto, the process comprising contacting the polymer with an aqueous treatment bath containing a hydrophilic polysiloxane polymer having a molecular weight greater than about 1000 g/mol under conditions sufficient to bond the polymer and hydrophilic polysiloxane while avoiding polymerization of the polymer with the hydrophilic polysiloxane polymer;
