in a particularly preferred embodiment of the disclosure the amino functional polysiloxane is prepared by a conventional polycondensation process comprising for example heating a mixture of silanol terminated dimethylsiloxane oligomers aminopropyl dimethoxymethylsilane and hexamethyldi siloxane endblocker in the presence of a catalyst then gradually reducing the pressure to promote condensation and removing water and methanol by products from the reaction mixture the catalyst can be selected from the group consisting of barium hydroxide trisodium orthophosphate or similar base catalysts polycondensation is achieved by heating the reaction mixture for a period of time typically the mixture is heated up to 85 u00b0 c for up to 3 hours the by products formed in the process are water and alcohol and they are removed by reducing the pressure typically down to 200 mbar and stripping them out of the reaction mixture after the viscosity of the product is stabilized the pressure is adjusted to ambient and the product is cooled in an inert atmosphere a similar procedure is used for the preparation of carbinol terminated polysiloxane where silanol terminated dimethylsiloxane oligomers are reacted under the same conditions with aminopropyldimethylmethoxysilane endblocker the reaction process is identical but the product of this reaction is a linear polydimethylsiloxane terminated with an amino functional radical the molecular weight of.
