Abstract
Description
本出願は、2013年12月19日出願の米国特許出願第61/918,326号の優先権を主張し、その全内容は、参照により本明細書に組み込まれる。
本発明の実施に使用される炭素−炭素(「C−C」)開始剤は、構造Iを有し
「第1のプロピレン系ポリマー」として使用されるプロピレン系ポリマーは、プロピレンホモポリマーとプロピレンインターポリマー及びコポリマーとの両方を含む。
本発明のビスブレーキングプロセスは、ビスブレーキング条件下、好ましくは酸素の不在下で、かつ典型的には不活性雰囲気下、例えば窒素下で、第1のプロピレン系ポリマーをC−Cフリーラジカル開始剤と接触させるステップを含む。ビスブレーキング条件は、典型的には、第1のプロピレン系ポリマーが溶融され、C−Cフリーラジカル開始剤が分解されて、フリーラジカルを形成する温度、例えば、200℃〜350℃、または200℃〜300℃、または210℃〜270℃を含む。一実施形態では、ビスブレーキング条件は、C−Cフリーラジカル開始剤を放射線に曝露することによってそれを分解または活性化させることを含む。
発明組成物は、1つ以上の添加剤を含んでもよい。添加剤としては、安定剤、帯電防止剤、顔料、染料、核形成剤、充填材、スリップ剤、難燃剤、可塑剤、加工助剤、潤滑剤、安定剤、煙抑制剤、粘度制御剤、ブロッキング防止剤、及びこれらの組み合わせが挙げられるが、これらに限定されない。典型的には、発明組成物は、1つ以上の安定剤、例えば、共にCiba Specialty Chemicalsにより供給されるIRGANOX 1010及びIRGAFOS 168などの抗酸化剤を含有する。ポリマーは、典型的には、押出または他の溶融プロセスの前に、1つ以上の安定剤で処理される。
反対のことが述べられない限り、文脈から暗に示されない限り、または当該技術分野における慣習でない限り、全ての部及びパーセントは重量に基づき、全ての試験方法は、本開示の出願日の時点で最新である。米国特許実務の目的で、特に定義(本開示で特別に提供されるいずれの定義とも矛盾しない程度に)及び当該技術分野における一般知識の開示に関して、いずれの参照される特許、特許出願、または公開の内容も、その全体が参照により組み込まれる(またはその等価の米国版がそのように参照により組み込まれる)。
i)ヘテロ原子、または
ii)少なくとも1つのヘテロ原子を含む、ペルオキシ基(−OOH)以外の基。
ヘテロ原子の非限定的な例としては、ハロゲン、窒素、硫黄、酸素が挙げられる。ペルオキシ基以外の基の非限定的な例としては、ハロアルキル、ヒドロキシ、アミノ、ホスフィド、アルコキシ、アミノ、チオ、ニトロ、及びこれらの組み合わせが挙げられる。
MFRとしても知られるメルトフローレート(グラム/10分またはdg/分)を、ASTM D 1238(230℃/2.16kg)に従って測定する。
ポリマー試料を、加熱したRS5000ドライブ及びHAAKE RHEOMIX 600混合器中で種々のレベルの指定の添加剤と溶融ブレンドした。充填レベル61%の混合チャンバを使用し、これはすなわち、チャンバの容積の61%を試料で充填したということである。使用した試料重量を、試料重量=材料のかさ密度(0.900g/cm3)×チャンバの実容積(69cm3)×充填率(0.61)〜37.9gとして近似した。
