Polysiloxane compound and method for manufacturing the same

A method for manufacturing a polysiloxane compound represented by the following formula (1),

• wherein, R1 represents a methyl group or a hydrogen atom, and “A” represents a group represented by the following formula (2) or (3),
• wherein, R's each independently represent a monovalent hydrocarbon group having 1 to 6 carbon atoms, “n” represents an integer of 1 to 200, and a broken line represents an atomic bonding,
• wherein, R's represent as described above, “a” represents an integer of 0 to 10, “b” represents an integer of 0 to 10, “c” represents an integer of 0 to 10, a+b+c represents 2 or more, and a broken line represents an atomic bonding,
• wherein the method for manufacturing the polysiloxane compound comprises a step of obtaining the polysiloxane compound represented by the formula (1) by a hydrosilylation of a compound represented by the following formula (4) having an unsaturated group at the terminal, and a hydrogensiloxane compound represented by the following formula (5) or (6),
• wherein, R1 represents as described above,
• wherein, R, “n”, “a”, “b”, and “c” represent as described above.
