Abstract
A composition, and article including such composition, wherein the composition includes a silsesquioxane polymer and a free siloxane; wherein the silsesquioxane polymer includes a three-dimensional network of Formula (I): wherein: each Rand Ris independently a (C1-C4)alkyl; each Land Lis independently a single bond, an alkylene, or an alkylene bonded to a group selected from oxy, thio, carbonyl, —NH—, and combinations thereof; each Ris independently a linear (C14-C100)alkyl; each R5 is independently a (C1-C30)alkyl, a (C1-C30)fluorinated alkyl, or a (C2-C30)heteroalkyl having at least one oxygen, sulfur, or —NH— group; with the proviso that L, L, and R5 are selected such that each Si atom is directly bonded to an alkylene or an alkyl; m is an integer of at least 2; n is an integer of 0 or above; m+n is an integer of at least 10; each oxygen atom at an asterisk (*) is bonded to another Si atom within the three-dimensional network; and the silsesquioxane polymer is a solid at 25° C.
