<p>A powder surface-treated with an organopolysiloxane represented by the following average compositional formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 1 a R 2 b R 3 c SiO (4-a-b-c)/2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R 1 is selected from the group consisting of C1-30 alkyl, C1-30 fluoroalkyl, C6-30 aryl, and C6-30 aralkyl groups,
R 2 is a group represented by the following formula (2), provided that R 2 is bonded to at least one terminal end of the organopolysiloxane when c equals 0,
R 3 is a group represented by the following formula (3):
wherein R 2 is as defined above, each R 8 is, independently, selected from the group consisting of C1-30 alkyl, C1-30 fluoroalkyl, C6-30 aryl, and C6-30 aralkyl groups, Q is C d H 2d or an oxygen atom, wherein d is an integer of from 1 to 5, k is an integer of from 0 to 500, and h is an integer of from 0 to 3,
a is a number of from 1.5 to 2.5,
b is a number of from 0.001 to 1.5, and
c is a number of from 0 to 1.5.</p> |
