Description
本出願は、2013年12月出願の米国特許仮出願第61/918,434号の利益を主張するものであり、この仮出願は、参照により本明細書に組み込まれる。
[−C(CH3)2−CH2−]n
として表すことができ、
式中、nは15〜75である。ポリイソブチレンなどの好ましい材料は、約200〜20,000m、約200〜5,000又は500〜3,000の分子量を伴う粘稠液体である。好ましい液体材料は、100℃で約100〜20,000のセイボルトユニバーサル秒(SUS)(Saybolt Universal seconds viscosity)粘度を有する。ポリイソブチレンに特有の特徴は、ガス透過性が低く、酸、アルカリ及び塩溶液の作用に対する耐性が高いことに加えて、誘電率が高いことである。これらの特徴は、太陽光又は紫外線の作用下で徐々に低下する(カーボンブラックを添加することによりこの過程は遅くなる。)産業上、ポリイソブチレンは、−80℃〜−100℃の温度でモノマーのイオン重合(AlCl3触媒)により製造される。これらは、ゴム産業で通常使用されている装置を使用して加工される。ポリイソブチレンは、天然又は合成ゴム、ポリエチレン、ポリ塩化ビニル、及びフェノール−ホルムアルデヒド樹脂と容易に混ざり合う。
第1非晶性コポリマー、第2相溶性コポリマー及び酸化防止剤を高温の混合条件にてブレンドすることにより完全に均質な溶解物を形成し、多数のホットメルト接着剤組成物を調製した。必要に応じて混合温度を約135〜約200℃、好ましくは約150〜約175℃の間で変化させ、均質性を得た。加熱した容器中で最終接着剤組成物を完全に均質化するため、在来型の加熱式撹拌ブレード(WiseStir、(登録商標))ミキサーを使用した。
ホットメルト接着剤組成物を後述するように溶融混練することによって配合した。特定の成分及び成分の量を次の表2に示す。
ホットメルト接着剤組成物を、後述のように溶解混錬により配合する。特定の成分及び成分の量を次表3に示す。
