CN111094478A 包含倍半硅氧烷聚合物和游离硅氧烷的组合物，以及制品 有权

包含倍半硅氧烷聚合物和游离硅氧烷的组合物，以及制品
Abstract:
本发明提供了一种组合物和包含此类组合物的制品，其中所述组合物包含倍半硅氧烷聚合物和游离硅氧烷；其中所述倍半硅氧烷聚合物包含式(I)的三维网络：其中：每个R1和R2独立地为(C1-C4)烷基；每个L1和L2独立地为单键，烷亚基，或键合到选自含氧基团、含硫基团、羰基、-NH-以及它们的组合的基团的烷亚基；每个R3独立地为直链(C14-C100)烷基；每个R5独立地为(C1-C30)烷基，(C1-C30)氟化烷基，或者具有至少一个氧、硫或-NH-基团的(C2-C30)杂烷基；前提条件是L1、L2和R5被选择成使得每个Si原子直接键合到烷亚基或烷基；m为至少2的整数；n为0或大于0的整数；m+n为至少10的整数；星号(*)处的每个氧原子键合到所述三维网络内的另一个Si原子；并且所述倍半硅氧烷聚合物在25℃下为固体。
Abstract(English):

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 R1 and R2 is independently a (C1-C4)alkyl; each L1 and L2 is independently a single bond, an alkylene, or an alkylene bonded to a group selected from oxy, thio, carbonyl, -NH-, and combinations thereof; each R3 is 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 L1, L2, 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.
