A novel double pH- and temperature-responsive tertiary amine starch ether (TAS) has been developed. Synthesis was performed by grafting dipropyl or dibutyl epoxypropylamine onto hydroxyethyl starch. The cloud point temperatures (TC) of TAS could be tuned to a wide range from 26 to 72.8°C by changing the alkyl chain length, their average molar substitution (MS), and pH value of the solution. The TC
The present invention concerns polysiloxanes having plural quaternary ammonium groups, their preparation and their use as softeners in the textile industry. Materials treated therewith exhibit a surprisingly high shear stability, an excellent, pleasant softness and improved sewability.
