Each R1 represents an alkylene group having from 1 to 4 carbon atoms, and at least some of the R1 groups are —CH2—CH2—CH2—CH2—. Each X group is independently represented by the formula CH2?C(R)—C(O)—O—V—W—C(O)—. The acrylic monomer having a carboxylic acid group is present in an amount of at least one percent and less than 20 percent by weight. Articles and methods using the composition are also described.
