METHOD FOR PRODUCING ALKYL SILICONE RESINS
A process for producing alkyl silicone resins (A) containing at least 80 wt % of units of the general formula (I), R1a(R2O)b(HO)dR3cSiO(4-a-b-c-d)/2 (I), is provided. Alkylalkoxysilane (A1) of the general formula (II), R1aR3cSi(OR2)(4-a-c) (II), is mixed in a first reaction step (R1), alternatively,...

| description | A process for producing alkyl silicone resins (A) containing at least 80 wt % of units of the general formula (I), R1a(R2O)b(HO)dR3cSiO(4-a-b-c-d)/2 (I), is provided. Alkylalkoxysilane (A1) of the general formula (II), R1aR3cSi(OR2)(4-a-c) (II), is mixed in a first reaction step (R1), alternatively, with a pure acid (S) having pKa of not more than 5, with an at least 5 wt % aqueous solution of an acid (S) having a pKa of not more than 5 or with a halosilane compound (A2) of the general formula (III), R1aR3cSi(X)(4-a-c) (III). Subsequently, in at least one further reaction step, (R2) water is added. |
