ADHESIVE COMPOSITIONS COMPRISING A SILSESQUIOXANE POLYMER CROSSLINKER, ARTICLES AND METHODS |
摘要 |
A pressure sensitive adhesive composition is described comprising at least one low Tg (meth)acrylic polymer, and at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The low Tg (meth)acrylic polymer typically has a Tg no greater than 10°C. In some embodiments, the low Tg (meth)acrylic polymer comprises at least 50, 55, 60, 65, or 70 wt-% of polymerized units derived from low Tg ethylenically unsaturated monomer(s). The low Tg ethylenically unsaturated monomer(s) is typically an alkyl (meth)acrylate comprising 4 to 20 carbon atoms. Also described are pressure sensitive adhesive articles and methods of preparing such articles. |
