BLOCK ABA SILICONE POLYALKYLENE OXIDE COPOLYMERS METHODS OF PREPARATION AND APPLICATIONS FOR EMPLOYING THE SAME

摘要

There is provided herein a linear tri block copolymer having the average formula (1 ): ABA (1 ) wherein A is a polyalkyleneoxide unit or an aliphatic modified polyalkyleneoxide unit both of the general formula: RO(CHO)Y and wherein B is an internal polysiloxane unit of the general formula: [X(CHO)R[SiO(R )]Si(R)R(OCHa)X] wherein X and Y are divalent organic groups selected from a secondary amine or a tertiary amine and a ring opened epoxide such that when X is a ring opened epoxide Y is a secondary or tertiary amine and when Y is a ring opened epoxide X is a secondary or tertiary amine. In addition there is provided herein a method of making a linear tri block copolymer having the average formula (1) and personal care and softener compositons comprising the same specifically a hair conditioner.
