このような問題の解決方法として、例えば特許文献1及び2には、特定の添加剤の組合せ及び処方によって添加剤のブリードアウトを制御する手法が記載されている。
本発明の課題は、添加剤のブリードアウトの環境依存性が少ないポリオレフィン系成形体を提供することにある。

添加剤は、樹脂中の非晶部分に存在している。基材樹脂が結晶化度の高いポリプロピレン(弾性率が500MPa以上である汎用ポリプロピレン)である場合、成形体の置かれた環境が高温下であると二次結晶化が進み、非晶部分が少なくなる。また、成形体の置かれた環境が高湿下であると水分との親和性の高い添加剤が表面に移行しやすくなる。その結果、非晶部分に存在していた添加剤が押し出されて成形体表面にブリードアウトすると考えられる。
本発明では、このような汎用ポリプロピレンに対して、弾性率が5~450MPaである結晶化度の低いオレフィン系重合体を所定量配合することで、樹脂組成物中の非晶部分を増加させることができると考えられる。また、当該オレフィン系重合体は、温度を上げても樹脂中の非晶部分の変化が少ないと考えられ、その結果、温度を上げても添加剤が押し出されにくく、添加剤のブリードアウトの環境依存性が少なくなると考えられる。
一般的には、低結晶性成分を増やすとブリードアウトが増加するのみと考えられる。そのため、本発明の効果は予期せぬ効果であると言える。
なお、本発明の効果発現の作用機構は以上の推定機構のみに限定されるわけではない。
以下、本発明の成形体を構成する樹脂組成物に含まれる各成分について説明する。

オレフィン系重合体としては、特にポリプロピレンが好ましい。該ポリプロピレンは、弾性率が5~450MPaである限り、プロピレン以外の上記α-オレフィンとの共重合体であってもよい。この場合、プロピレン以外のα-オレフィンの使用比率は、プロピレン及びそれ以外のα-オレフィンの全量に対して好ましくは2質量%以下、より好ましくは1質量%以下である。

(d)[mm]×[rr]/[mr]2≦2.0
(e)重量平均分子量(Mw)=10,000~500,000
(f)分子量分布(Mw/Mn)<4
(g)示差走査型熱量計(DSC)を用いて、窒素雰囲気下-10℃で5分間保持した後10℃/分で昇温させることにより得られた融解吸熱カーブの最も高温側に観測されるピークのピークトップとして定義される融点(Tm-D)が0~120℃である。
以下に、上記特性(a)~(g)について順に説明する。
本発明で好ましく使用される低結晶性ポリプロピレンは、[mmmm](メソペンタッド分率)が好ましくは20~60モル%である。[mmmm]が20モル%以上であれば、溶融後の固化が遅くならず、樹脂組成物がベタつくのを抑制できるため、添加前後での質感に変化が無くなる。また、[mmmm]が60モル%以下であれば、結晶化度が高過ぎることがなく、ブリードアウトの環境依存性の制御に必要な非晶成分の量が十分な量存在する。このような観点から、[mmmm]は、好ましくは30~55モル%、より好ましくは40~55モル%である。
本発明で好ましく使用される低結晶性ポリプロピレンは、[rrrr]/(1-[mmmm])が好ましくは0.1以下である。[rrrr]/(1-[mmmm])は、低結晶性ポリプロピレンの規則性分布の均一さを示す指標である。この値が大きくなるとチーグラー触媒系を用いて製造されるポリプロピレンのように高立体規則性ポリプロピレンとアタクチックポリプロピレンとの混合物となり、べたつきの原因となる。このような観点から、[rrrr]/(1-[mmmm])は、好ましくは0.001~0.05、より好ましくは0.001~0.04、更に好ましくは0.01~0.04である。なお、上記(b)における[rrrr]及び[mmmm]は、モル%単位の数値ではなく、通常の比率として計算する。

本発明で好ましく使用される低結晶性ポリプロピレンは、分子量分布(Mw/Mn)が好ましくは4未満である。分子量分布が4未満であれば、成形性の低下が抑制される。この分子量分布は、好ましくは3以下、より好ましくは2.5以下、更に好ましくは1.5~2.5である。
本発明で使用される低結晶性オレフィン系重合体(1)の融点(Tm-D)は、添加剤のブリードアウトの観点から、好ましくは0~120℃、より好ましくは20~120℃、更に好ましくは20~100℃、より更に好ましくは40~100℃、より更に好ましくは50~90℃、特に好ましくは60~80℃である。
なお、本発明では、示差走査型熱量計(パーキン・エルマー社製、DSC-7)を用い、試料10mgを窒素雰囲気下-10℃で5分間保持した後、10℃/分で昇温させることにより得られた融解吸熱カーブの最も高温側に観測されるピークのピークトップを融点(Tm-D)とする。
本発明で用いられる低結晶性オレフィン系重合体(1)の製造方法としては、(A)2個の架橋基を介して架橋構造を形成している遷移金属化合物と(B)助触媒を組み合わせて得られるメタロセン触媒を用いてプロピレン等の前記α-オレフィンを重合又は共重合する方法が好ましい。
具体的には、下記一般式(i)で表される遷移金属化合物(A)、及び該(A)成分の遷移金属化合物又はその派生物と反応してイオン性の錯体を形成しうる化合物(B-1)及びアルミノキサン(B-2)から選ばれる助触媒成分(B)を含有する重合用触媒の存在下、プロピレン等の前記α-オレフィンを重合又は共重合させる方法が挙げられる。
本発明では、基材樹脂として、弾性率が500MPa以上であるプロピレン系重合体が用いられる。当該プロピレン系重合体は、立体規則性が高いプロピレン系重合体である。以下、「弾性率が500MPa以上であるプロピレン系重合体」を「高結晶性プロピレン系重合体」とも称する。
また、本発明で使用される高結晶性プロピレン系重合体(2)のメルトフローレート(MFR)は、好ましくは1~100g/10分、より好ましくは10~80g/10分、更に好ましくは15~80g/10分、特に好ましくは15~50g/10分である。
本発明で使用される高結晶性プロピレン系重合体(2)は、例えば特開2006-103147号公報等に記載の方法により製造することができる。
本発明で使用される添加剤(3)としては、ブリードアウトさせることが有用な添加剤であれば特に制限はなく、従来公知の添加剤を使用することができる。なお、添加剤は、直接、液体や固体粉末を樹脂に配合してもよいが、取り扱い性、計量性、分散性の観点から、マスターバッチの形態で樹脂に配合することが好ましい。
添加剤の具体例としては、発泡剤、結晶核剤、耐侯安定剤、紫外線安定剤(紫外線吸収剤)、光安定剤、耐熱安定剤、帯電防止剤、帯電剤、離型剤、難燃剤、合成油、ワックス、電気的性質改良剤、スリップ剤、アンチブロッキング剤、粘度調整剤、着色防止剤、防曇剤、滑剤、顔料、染料、可塑剤、軟化剤、老化防止剤、塩酸吸収剤、塩素捕捉剤、酸化防止剤、粘着防止剤等が挙げられる。中でも、帯電防止剤、離型剤、電気的性質改良剤、光安定剤、紫外線安定剤、スリップ剤、アンチブロッキング剤、防曇剤及び粘着防止剤から選択される少なくとも1種が好ましく、帯電防止剤が特に好ましい。
紫外線安定剤としては、公知の紫外線安定剤を用いることが可能である。該紫外線安定剤としては、ベンゾトリアゾール系、ベンゾフェノン系、サリシレート系、シアノアクリレート系、ニッケル系、トリアジン系が例示できる。例えば、ベンゾトリアゾールが挙げられる。
スリップ剤としては、公知のスリップ剤を用いることが可能である。該スリップ剤としては、高級脂肪酸アミドが例示できる。例えば、エルカ酸アミドが挙げられる。
本発明の成形体を構成する樹脂組成物における低結晶性オレフィン系重合体(1)の含有量は、1~30質量%であり、好ましくは2~20質量%、より好ましくは3~10質量%である。低結晶性オレフィン系重合体(1)の含有量が1質量%未満であると、添加剤のブリードアウトに対する効果が乏しく好ましくない。また、30質量%を超えると、樹脂組成物の物性を大きく低下させるため好ましくない。
前記樹脂組成物に他の熱可塑性樹脂を含有させる場合、樹脂組成物における他の熱可塑性樹脂の含有量は、好ましくは30質量%以下、より好ましくは20質量%以下、更に好ましくは10質量%以下、特に好ましくは5質量%以下である。
なお、本発明の成形体を構成する樹脂組成物における前記高結晶性プロピレン系重合体(2)の含有量は、それ以外の各成分の含有量を100質量%から差し引いた「残部」となる。
本発明のポリオレフィン系成形体は、下記物性(a)と物性(b)との比((a)/(b))が0.75~1.35であり、好ましくは0.8~1.25、より好ましくは0.9~1.1である。
(a)成形直後から、温度23℃湿度50%の環境下に7日間保管した成形体の、添加剤由来の物性
(b)成形直後から、温度40℃湿度90%の環境下に7日間保管した成形体の、添加剤由来の物性
本発明のポリオレフィン系成形体は、添加剤のブリードアウトの環境依存性が少ない。そのため、成形体の使用される温度及び湿度環境によって変動する影響を考慮する必要がなく、成形体の製造時における添加剤の処方を一定とすることができる。
(a’)成形直後から、温度23℃湿度50%の環境下に1日間保管した成形体の、添加剤由来の物性
(b’)成形直後から、温度40℃湿度90%の環境下に1日間保管した成形体の、添加剤由来の物性
一般に、ポリオレフィン系樹脂組成物は極性がないため帯電しやすく、塵芥が付着しやすい。帯電防止剤を樹脂組成物に添加してシート又はフィルムに成形することで、帯電防止剤がシート又はフィルムの表面にブリードアウトして防塵効果を奏することが可能である。しかしながら、一般に高温高湿になると添加剤はブリードアウトしやすいため、シート又はフィルムの保管又は使用される温度及び湿度環境によっては、帯電防止剤がブリードアウトしすぎて白濁やベタつきが発生するおそれがある。そのため、従来は、シート又はフィルムの置かれうる環境に応じて、その製造時における帯電防止剤の添加量を決定している。
これに対して、本発明のポリオレフィン系成形体は、添加剤のブリードアウトの環境依存性が少ない。そのため、成形体、特にシート又はフィルムにおいて、使用される温度及び湿度環境によって添加剤のブリードアウト量が変動する心配が不要であり、添加剤の処方を一定とすることができる。
一般に、ポリオレフィン系樹脂組成物は極性がないため分子間相互作用によって互いが接触すると高い摩擦係数を生じやすい。スリップ剤を樹脂組成物に添加してシート又はフィルムに成形することで、スリップ剤がシート又はフィルムの表面にブリードアウトして摩擦低下効果を奏することが可能である。しかしながら、一般に高温高湿になると添加剤はブリードアウトしやすいため、シート又はフィルムの保管又は使用される温度及び湿度環境によっては、スリップ剤がブリードアウトしすぎて白濁やベタつきが発生するおそれがある。そのため、従来は、シート又はフィルムの置かれうる環境に応じて、その製造時におけるスリップ剤の添加量を決定している。
これに対して、本発明のポリオレフィン系成形体は、添加剤のブリードアウトの環境依存性が少ない。そのため、成形体、特にシート又はフィルムにおいて、使用される温度及び湿度環境によって添加剤のブリードアウト量が変動する心配が不要であり、添加剤の処方を一定とすることができる。
本発明のポリオレフィン系成形体は、前記樹脂組成物を成形することで得ることができる。
本発明の成形体としては、フィルム、シート、容器、自動車内装材、架電製品のハウジング材等が挙げられる。フィルムとしては、食品包装用フィルムや農業用フィルム(ビニールハウスの例)等が挙げられる。容器としては、透明性に優れているので、透明ケース、透明ボックス、化粧箱等が挙げられる。
本発明の成形体は、単位グラム当たりの表面積が好ましくは1×10-8~10m2/g、より好ましくは1×10-7~5m2/g、更に好ましくは1×10-6~1m2/gである。上記好ましい範囲の表面積を満たす成形体において、帯電防止剤を添加することによる防塵効果やスリップ剤を添加することによる摩擦低下効果が顕著である。

〔樹脂組成物の製造〕
製造例1で得られた低結晶性ポリプロピレン5質量%、高結晶性ポリプロピレン(PP、プライムポリマー(株)製、商品名:F-704NP)94質量%、ステアリン酸モノグリセリド8質量%からなる帯電防止剤マスターバッチ1質量%の配合比で溶融混練することで樹脂組成物を得た。なお、高結晶性ポリプロピレンについて上記と同様にして初期弾性率を算出したところ、1600MPaであった。
得られた樹脂組成物を用いて、50mmφTダイキャスト成形機(サーモ・プラスティックス工業(株)製)により、下記の成形条件で膜厚400μmのシートを製膜した。
Tダイ出口温度:230℃
チルロール:梨地
チルロール温度:30℃
引き取り速度:1.2m/min
シートの品質は、製膜後、温度23℃湿度50%又は温度40℃湿度90%の環境下で1日又は7日間エージング処理を行った後、温度23℃湿度50%で、1時間以上の状態調節の後、同じ温度、湿度条件下にて表面固有抵抗測定を行った。表面固有抵抗は、JIS K6911に従い測定した。表面固有抵抗の値は、常用対数に換算した。表面固有抵抗の値は、小さいほど、添加剤のブリードアウト量が多いことを示す。結果を表4に示す。

これに対して、実施例1~3では、保管環境が異なる場合でも表面固有抵抗値の変動の幅が小さく、このことからブリードアウトの環境依存性が少ないことがわかる。
帯電防止剤マスターバッチに代えて、エルカ酸アミド10質量%を含有するスリップ剤マスターバッチを用いたこと以外は実施例2と同様にして、樹脂組成物を得た。また、得られた樹脂組成物を用いたこと以外は実施例2と同様にしてシートを製膜した。
