Abstract
Description
本願は、2016年6月30日に出願された米国特許仮出願第62/356,985号の利益を主張する。この仮出願特許は参照によりその全体が本明細書に組み込まれる。
本開示での使用に好適するスチレン系ブロックコポリマーを作製し、試料1及び試料2と命名した。特に、試料1はスチレンのアニオン重合、及びその後、微細構造制御剤の存在下でブタジエンのアニオン重合に続けて、カップリングとその後の水素添加により作製した。生成したポリスチレンの分子量は、GPCによって5.6kg/molであると求められた。ブタジエン重合の終わりに収集した試料は、約13重量%のスチレン分で、1H NMRに基づいて71.1%のビニル分であり、GPCにより求めて、215kg/molの全体分子量であった。スチレン及びブタジエンをカップリングして、最終生成物をカップリング効率92.3%で形成した。その後、スチレン系ブロックコポリマーの試料を水素添加した。
本明細書で開示のタイプのIPCの特性を調査した。具体的には、スチレン系ブロックコポリマー及びポリプロピレンを70:30の重量比で含むIPC試料を作製した。表3は、これらの組成物の種々の特性を示し、実施例1、試料1及び試料2由来のスチレン系樹脂ポリマーを含むIPCをそれぞれ組成物4及び5と命名する。試験片を射出成形プラークから切り出し;配合物#2及び#3を230℃で射出成形し、配合物#4及び#5を210℃で射出成形した。組成物1はPVCを含み、組成物2は実施例1の試料3を含み、組成物3は市販の水素添加熱可塑性ゴムを含む。
試料1及び3の弾性を調査し、結果を表4に示す。
接着剤配合物におけるIPCの利点を調査した。具体的には、IPCを含むホットメルト接着剤配合物の特性を測定した。表5は、代表的配合物及び試験結果を示す。
