POLYSILOXANE-N, N-DIHYDROCARBYLENE SUGAR-MODIFIED MULTIBLOCK COPOLYMER AND METHOD FOR PRODUCING THE SAME

摘要

The present invention provides a novel and stable organopolysiloxane, which has both hydrophobic properties and hydrophilic properties and exhibits reduced hydrolysis properties, and provides a preparation method capable of easily synthesizing the aforementioned organopolysiloxane without using complicated and/or troublesome operations. A polysiloxane-N, N-dihydrocarbylene sugar-modified multiblock copolymer is obtained by reacting a polysiloxane- hydrocarbylene aminohydrocarbylene multiblock copolymer having a secondary amino group with a sugar acid or an intramolecular dehydration cyclic product thereof.
