Abstract:
1. A siloxane-based polymer having repeat units of a cyclic Si—O structure, prepared by hydrolyzing and polycondensing at least one multi-functional cyclic siloxane compound of formula (1) alone, or in combination with at least one monomer selected from the group consisting of the compounds of formulas (2)-(5), in an organic solvent in the presence of an acid or alkali catalyst and water: wherein, R R p is an integer from 3 to 8, wherein, R each of X m is an integer from 0 to 10; and p is an integer from 3 to 8, wherein, each of X M is a single bond, a C wherein, R R n is an integer from 0 to 3, and wherein, each of R n is an integer from 0 to 30.
