ホモ活性(固体触媒成分1g当たりの重合活性)については、下記式(3)により求めた。

このときの重合活性や、得られた共重合体の物性を実施例6と同様の方法で測定した。
結果を表3に示す。
また、表3より、実施例8で用いた本発明に係るオレフィン類重合用触媒は、上記特定の成分を含むものであることにより、内部電子供与性化合物としてフタル酸エステル以外の化合物を含むオレフィン類重合用固体触媒成分を含有するものであるにも拘わらず、得られた共重合体のブロック率及びEPRに優れるとともに、共重合体の曲げ弾性率(FM)及びIZOD衝撃強度にも優れるものであることが分かる。
また、表3より、比較例3で用いたオレフィン類重合用触媒は、外部電子供与性化合物として特定のアミノシラン化合物以外の化合物を使用していることから、実施例6と比較したときに、得られた共重合体のブロック率及びEPRが低く、共重合体のIZOD衝撃強度も低いものであることが分かる。
