    摘要: An adhesive composition containing the polymer derived from the polyether-containing monomer is provided. More specifically, the polyether-containing macromer having a urea (—NH—(C═O)—NH—) or carbamate (—NH—(C═O)—O—) linkage between the polyether group and a (meth)acryloyl group. The adhesive composition is typically a pressure-sensitive adhesive. Additionally, an article is provided that contains the adhesive composition positioned adjacent to a substrate. The articles can be, for example, an adhesive tape or can be part of another article that is flexible and foldable such as, for example, an electronic device that is flexible and/or foldable. The adhesive compositions can be tolerant of high temperature and high humidity conditions (e.g., 65 degrees Celsius and 90 percent relative humidity for 14 days).

    摘要: Alkali-swellable rheology modifier comprising a core-shell polymer comprising a core polymer and a shell comprising at least one shell copolymer layer at least partially cross-linked and containing a mole percent of crosslinking agent greater than the mole percent of crosslinking agent in the core polymer, provided if the mole percent of crosslinking agent in the core polymer is zero, then either the core polymer is greater than 60 wt % of the core-shell polymer; the core polymer comprises at least one associative monomer; at least one shell copolymer layer copolymer comprises at least one associative monomer; and/or the at least one shell copolymer layer that is at least partially cross-linked comprises greater than 3 mole% crosslinking agent. Aqueous compositions comprising the alkali-swellable rheology modifier include personal care formulations, healthcare formulations, agricultural formulations, paint formulations, coating formulations, laundry and fabric care formulations, household cleaning formulations, and industrial and institutional cleaning formulations.
