<p>The present invention relates to compounds represented by the following Formula I, in which R1-R6 can each independently be selected from hydrogen or hydrocarbyl (e.g., methyl); L1 is a divalent linking group, such as a bond or -OC(O)-R8-C(O)O, where R8 can be divalent hydrocarbyl (e.g., -CH2CH2-); each L2 independently represents a flexible segment, such as divalent linear or branched C1-C25 alkyl; each L3 independently represents a rigid segment including, for example, optionally substituted phenylen-1,4-diyl groups; t is from 1 to 4; m and p are each independently from 0 to 4 for each t, provided that the sum of m and p is at least 1 for each t; and E can be hydrogen or hydrocarbyl. The present invention also relates to compositions and articles that include the compound represented by Formula I.</p> |
