Description
log(K/K0)=ρσ (x)
(式中、Kは置換基を有する化合物の反応値を表し、K0は前記化合物が置換基を有さな
い場合、すなわち置換基が水素原子である場合の化合物の反応値を表し、ρは反応定数を表し、σは置換基定数を表す。)によって表される。
2003)の第7章に記載されている。主な官能基についての、Fdi,Fpi、EhiおよびVを表1に示した。
(1)圧縮変形量(mm)
ゴルフボールに初期荷重98Nを負荷した状態から終荷重1275Nを負荷したときまでの圧縮方向の変形量(圧縮方向にゴルフボールが縮む量)を測定した。
各ゴルフボールに198.4gの金属製円筒物を40m/秒の速度で衝突させ、衝突前後の前記円筒物およびゴルフボールの速度を測定し、それぞれの速度および質量から各ゴルフボールの反発係数を算出した。測定は各ゴルフボールについて12個ずつ行って、その平均値をそのゴルフボールの反発係数とした。なお、反発係数は、ゴルフボールNo.7の反発係数との差で示した。
表2に示す配合のゴム組成物を混練ロールにより混練し、半球状キャビティを有する上下金型内で170℃、20分間加熱プレスすることにより直径39.8mmのコアを得た。なお、評価するゴルフボールの圧縮変形量が同一(3.5mm)になるように、コア配合を調整した。
アクリル酸亜鉛:日本蒸溜工業社製、「ZNDA−90S」
酸化亜鉛:東邦亜鉛社製、「銀嶺(登録商標)R」
ジクミルパーオキサイド(DCP):日油社製、「パークミル(登録商標)D」
次に、表3に示した配合のカバー用材料を、二軸混練型押出機により押し出して、ペレット状のカバー用組成物を調製した。押出は、スクリュー径45mm、スクリュー回転数200rpm、スクリューL/D=35で行った。配合物は、押出機のダイの位置で150〜230℃に加熱された。得られたカバー用組成物を上述のようにして得られたコア上に射出成形して、コアと前記コアを被覆するカバー(厚み1.45mm)を有するゴルフボールを作製した。得られたゴルフボールの反発係数を評価した。評価結果を併せて表2に示した。
