Hydrophilic polysiloxane elastomer

An elastomer has the general structure of:where: subscript a is 50-500, b is 1-10, c is 2-30, R1 has the structure:-CH2(CH2)nO(CH2)pCH(OH)(CH2)qNR2R2′where n, p and q are each independently 1-5 and R2 and R2′ are independently selected from alkyl and hydroxyalkyl groups having 1-5 carbon atoms; wher...

Beschreibung
Zusammenfassung:	An elastomer has the general structure of:where: subscript a is 50-500, b is 1-10, c is 2-30, R1 has the structure:-CH2(CH2)nO(CH2)pCH(OH)(CH2)qNR2R2′where n, p and q are each independently 1-5 and R2 and R2′ are independently selected from alkyl and hydroxyalkyl groups having 1-5 carbon atoms; where X is a crosslinker remnant bound to a siloxane unit corresponding to subscript c of a siloxane backbone polymer in addition to the one shown so that the crosslinker remnant in each occurrence is a reaction product with two siloxane backbone polymers, wherein the crosslinker is selected from a group consisting of primary organic dienes, divinyl siloxane and polyoxyalkylenes wherein at least two X components correspond to crosslinker remnants connecting the same two siloxane backbone polymers.
