このアクリルポリマーは、場合により、高ガラス転移温度(即ち、約0℃より高いTg)を有するモノマーを含む他の周知のコモノマーを更に含む。非限定例には、メチルアクリレート、メチルメタクリレート、エチルアクリレートおよび/またはイソブチルメタクリレートが挙げられる。他のコモノマーは、アクリルポリマーのTgを変えるために使用し得る。このようなコモノマーには、N−ビニルピロリドン、N−ビニルカプロラクタム、t−オクチルアクリルアミドなどのN−アルキル(メタ)アクリルアミド、シアノエチルアクリレート、ジアセトンアクリルアミド、N−ビニルアセトアミド、N−ビニルホルムアミド、グリシジルメタクリレートおよびアリルグリシジルエーテルが挙げられる。
用語「薬物」は、本明細書では、治療上の何らかの利点をもたらすことを意図する任意の薬剤を意味するように、その最も広い意味で解釈すべきである。この薬剤は、医薬として活性であってもなくてもよいが、これが人体に対して効果があるという意味では「生体活性」であろう。この薬剤は、病気かまたはそうでない可能性のある状態、即ち病態を治療するかまたは変えるために使用してもよい。「薬物」、「生体活性薬剤」、「製剤」、「薬剤(medicament)」、「治療薬」、「生理作用物質」および「薬剤(pharmaceutical agent)」は、本明細書では互換的に使用でき、これらには、病状もしくは病態の診断、治癒、軽減、停止、治療もしくは予防に使用するための、または体の構造もしくは機能に影響を及ぼすための物質が挙げられる。この用語には、例えば、柔軟化および保湿化するように作用する皮膚健全剤(skin−wellness agent)が含まれる。用語「治療」は、病態の予防、変更、治癒および制御を包含するように広く使用される。
