Description
本出願は、2009年7月8日に出願された米国特許出願第12/499667号の優先権を主張する。米国特許実施のため、これらの出願の内容を全体として参照により本明細書に組み入れる。
(a)Mw/Mn約1.7から約3.5、少なくとも1つの融点Tm(℃)、及び密度d(g/cm3)を有し、Tm及びdの数値は、下記の関係に対応し、
Tm>−2002.9+4538.5(d)−2422.2(d)2、又は
(b)Mw/Mn約1.7から約3.5を有し、融解熱ΔH(J/g)、及び最高DSCピークと最高CRYSTAFピークとの温度差として定義されるデルタ量ΔT(℃)によって特徴づけられ、ΔT及びΔHの数値は下記の関係を有し、
ΔHが0超から130J/gまでの場合、ΔT>−0.1299(ΔH)+62.81、
ΔHが130J/gを超える場合、ΔT≧48℃、
ここでCRYSTAFピークは、少なくとも5%の累積ポリマーを用いて求められ、5%未満のポリマーが識別可能なCRYSTAFピークを有する場合、CRYSTAF温度は30℃であり、又は
(c)エチレン/α−オレフィンインターポリマーの圧縮成形フィルムを用いて測定される300%歪み及び1サイクルでの弾性回復率Re(%)によって特徴づけられ、密度d(g/cm3)を有し、Re及びdの数値は、エチレン/α−オレフィンインターポリマーが実質的に架橋相を含まないとき、下記の関係を満たし、
Re>1481−1629(d)、又は
(d)TREFを用いて分画したとき、40℃から130℃で溶出する分子画分を有し、該画分が、同じ温度の間に溶出する同等のランダムエチレンインターポリマー画分より少なくとも5%高いコモノマーモル含量を有し、ここで前記の同等のランダムエチレンインターポリマーは、同じコモノマー、並びにエチレン/α−オレフィンインターポリマーの10%以内のメルトインデックス、密度、及びコモノマーモル含量(全ポリマーに対する)を有することを特徴とし、又は
(e)25℃での貯蔵弾性率G’(25℃)及び100℃での貯蔵弾性率G’(100℃)によって特徴づけられ、G’(25℃)とG’(100℃)の比は、約1:1から約10:1であり、好ましくは、エチレン/α−オレフィンブロックインターポリマーは中間相分離しており、例えばマルチブロックに関しては、PCT/US09/032699及び米国特許仮出願第61/024674号に記載されており、制御配列分布例(ジブロック)は、PCT/US09/032705及び米国特許仮出願第61/024688号である。
(a)材料の総重量に対して0重量%超から約90重量%の量の少なくとも1種の充填剤であって、充填剤が、石炭フライアッシュ、ATH、CaCO3、タルク、再生ガラス、水酸化マグネシウム、粉砕(ground up)タイヤ、及び粉砕カーペットからなる群から選択される充填剤、
(b)場合により、MAH−g−HDPE、EEA、及びEAAからなる群から選択された少なくとも1種の他のポリマー、
(c)場合により、少なくとも1種の油、
(d)場合により、着色添加剤、例えばカーボンブラック、並びに
(e)0から約15重量パーセントの少なくとも1種の粘着付与剤を含む、本発明のカーペット又はカーペットタイルが開示される。
増大膨張力は、TA Instrument RSA III(RheometricSolids Analyzer III)を用いて測定する。厚さ0.8〜1mmの各サンプルの圧縮成形シートを、幅12.7mmの長方形に切断し、計器に装填する。試験中、クランプの距離(長さ)が20mmに固定されるように、歪み(strain)及び張力(tension)を設定する。温度傾斜は、室温から溶融まで20℃/分で動くようにプログラムする。温度傾斜中の力を記録し、式1に従ってそこから増大膨張力を算出する。
式中、σは増大膨張力であり、Fは増大力であり、Areaはフィルム断面積であり、tはフィルム厚さであり、Wはフィルム幅である。40℃での増大膨張力の値を、異なるサンプル間の比較に用いる。各サンプルに関して、この手順を3回行い、平均増大膨張力を報告する。
残留応力特性は、Instronを用い、ASTM D1708サンプル形状の小引張試験片を用いて測定する。サンプルは、100%/分で25%まで引き、25%で30分間保持し、その間、応力を時間と共に記録する。試験は環境室で行い、設置により経験する可能性のある極端な温度に対応するため40℃に設定する。30分後の残留応力率を、異なるサンプル間の比較に用いる。各サンプルに関して、この手順を2回行い、平均残留応力を報告する。
エチレン/1−オクテンマルチブロックコポリマーの他の特性には、下に記載したものが含まれる。
比較例1は上記と同じ配合である。
実施例1は上記と同じ配合である。
ガラス充填剤:ガラス粉末は、典型的に使用済みガラス製品、具体的には厚板ガラスとして公知である自動車用及び建築用ガラスを再生利用することによって生成される。しかしながら、他の種類のガラス、例えばフリントガラス、Eガラス、ホウケイ酸ガラス、茶ガラス(瓶ガラス)、及び緑ガラス(瓶ガラス)、及びそれらの組み合わせもガラス粉末を形成するために用いることができる。したがって、適切な粘度を維持しながら、充填剤中にガラス粉末の適切な分散を確実に得るために、ガラス粉末の平均サイズは、約100メッシュから400メッシュであることができる。より具体的には、いくつかの実施形態において、ガラス粉末の平均サイズは、約200メッシュであることができる。
PSA及びHMA組成物の適切な範囲は、以下のとおりである。
充填剤:40〜70%
粘着付与樹脂 20〜40%
油 0〜10%
OBC 100%となる残量
