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.
A polymer with enhanced hydrophilicity and thermal regularize properties, said polymer having recurring amide groups as an integral part of the main polymer or copolymer chain, said polymer having bonded thereto an hydrophilic anionic polysiloxane polymer having a molecular weight greater than about 1000 g/mol and having an affinity for said aliphatic polyamide polymer, and said polymer having substantially no polymerization with the hydrophilic anionic polysiloxane polymer, said hydrophilic anionic polysiloxane polymer having the formula ##STR3## wherein X is selected from the group consisting of phosphate, phosphonate, phosphorylate, sulfonate, sulfate, sulfone and carboxylate groups;
A polyester polymer having enhanced hydrophilicity and thermal regularity 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 polysiloxane polymer, said hydrophilic anionic polysiloxane polymer having the formula ##STR4## wherein X is selected from the group consisting of phosphate, phosphonate, phosphorylate, sulfonate, gulfate, gulfone and carboxylate groups;
A process of treating a polyester polymer or a polymer having recurring amide groups as an integral part of the main polymer or copolymer chain to impart hydrophilicity and thermal regulative properties thereto, the process comprising contacting the polymer with an aqueous treatment bath containing a hydrophilic anionic polysiloxane polymer having a molecular weight greater than about 1000 g/mol under conditions sufficient to bond the polymer and the hydrophilic anionic polysiloxane polymer while avoiding polymerization of the polymer with the hydrophilic anionic polysiloxane polymer, wherein the hydrophilic anionic polysiloxane polymer has the formula ##STR5## wherein X is selected from the group consisting of phosphate, phosphonate, phosphorylate, sulfonate, sulfate, sulfone and carboxylate groups;
