Abstract
Description
本発明は、一般的に、エラストマー性エチレン/アルファ(α)−オレフィン(EAO)ポリマーまたはEAOポリマー配合物、および高融点プロピレンポリマーを含有するレオロジーが改質された熱可塑性エラストマー(TPE)組成物、該組成物の製造、製品を作るための異形押出しおよび射出成形のようなプロセスにおける該組成物の使用、並びに得られた製品に関する。本発明は、さらに詳しくは、両成分が酸化物改質された組成物、該成分の物理的配合物を改質するための過酸化物の使用による等の該組成物の製造方法、並びに、射出成形による作業長靴のシャフト、異形押出しによる冷蔵庫のガスケット、およびシート押出しおよび/またはカレンダ加工、ついで熱成形による自動車用スキンのような薄い壁のある部品を含む加工品を製造するための該組成物の使用に関する。
エラストマー性部品の製造者は、一層高い生産性、改良された品質、および一層広い市場のいずれか、またはすべてを得ることができる加工特性を有するエラストマーに対する継続している研究に従事している。このような部品を製造するために使用される慣用のプロセスは、これに限定されるものではないが、射出成形プロセス、異形押出しプロセス、フィルム押出しプロセス、インフレーションフィルム(blown film)プロセス、シート押出しプロセスを含む。どのような配合物または組成物が加工するかの4つの有用な基準は、ずり減粘インデックス(STI)、溶融強度(MS)、凝固温度(ST)、および高い方の使用温度(UST)である。これらの特性の改良は、このようなエラストマー性部品に関する生産性、品質、および市場の大きさに直接影響する。
過酸化物の添加によるなどのレオロジー改質は、EAOポリマーのSTまたはUST限界に効果がなくても、少なくとも1種のエラストマー性EAOポリマーまたはEAOポリマー配合物と、PPのような高融点ポリオレフィンとの配合物のSTおよびUST限界に劇的な効果をもたらすことが、驚くべきことにここで見出された。さらに、このような配合物のレオロジー改質は、(a)レオロジー改質されたEAOポリマーもしくはEAOポリマー配合物、または(b)レオロジー改質なしの、同一の高融点ポリオレフィンとEAOポリマーまたはEAOポリマー配合物との配合物のSTIを超えるSTIをもたらす。
本発明の組成物は、上記のプロセスのような慣用のポリマー加工プロセスを用いて、種々の造形品を形成することができる。適当な造形品の、完全からは遠いが部分的な列挙は、自動車の車体部品および非自動車部品の両方を含む。自動車部品は、バンパーフェーシア、車体側方モールディング、外装部品、内装部品、通気遮断壁、エアダクト、ホイールカバー、並びにインストルメントおよびドアパネルスキンを含む。非自動車部品または用途は、ポリマーフィルム、ポリマーシート、ごみ入れ、貯蔵コンテナ、足びれ、ローンファニチャーストリップまたはウェッブ、芝刈り機および他のガーデン器具部品、レクリエーション用自動車部品、ゴルフカート部品、実用カート部品、並びに船舶部品を含む。組成物は、屋根膜のような屋根用途に使用されることもできる。その組成物は、さらに、長靴、特に工業用作業長靴用のシャフトのような履物の部品の加工において使用されることができる。当業者は、過度の実験なしにこの列挙を容易に増すことができる。
以下の実施例は本発明を具体的に説明するが、明示的にも黙示的にも本発明を限定するものではない。他に記載されない限り、すべての部(pbw)およびパーセント(wt%)は、総重量を基準とした重量による。本発明の実施例(Ex)は、アラビア数字で特定され、アルファベットの文字は比較例を特定する(比較例Ex)。
Claims (1)
- 少なくとも1種のエラストマー性EAOポリマーまたはEAOポリマー配合物と、ポリプロピレンホモポリマーおよびプロピレン/エチレンコポリマーから選択された少なくとも1種の高融点ポリマーとを含有する、レオロジー改質された、実質的にゲルなしのTPE組成物であり、該組成物は4つの特性の少なくとも3つを有し、該特性は、STI≧20、レオロジー改質なしの組成物のMSの≧1.5倍のMS、レオロジー改質なしの組成物のSTを≧10℃超えるST、およびレオロジー改質なしの組成物のUST限界を≧10℃超えるUST限界であることを特徴とするTPE組成物。
