Description
(a)コアポリマーであって、
(i)構造(I)のモノマー、構造(II)のモノマー、およびそれらの混合物から選択される1つ以上のモノマーの重合単位と、
(ii)1つ以上のモノビニルアクリルモノマーの重合単位と、
(iii)ケイ素原子を有しない1つ以上のグラフトリンカーの重合単位と、を含む、コアポリマーと、
(b)1つ以上のアクリルモノマーの重合単位を含むシェルポリマーと、を含む、ポリマー粒子である。
(A)水性媒体中に分散した液滴の集合体を含むエマルジョン(E1)にフリーラジカル重合(A)を行って、水性媒体中にコアポリマー粒子の分散液(D1)を形成することであって、液滴が、
(i)構造(I)のモノマー(上で定義されたもの)、構造(II)のモノマー(上で定義されたもの)、およびそれらの混合物から選択される1つ以上のモノマーと、
(ii)1つ以上のモノビニルアクリルモノマーと、
(iii)ケイ素原子を有しない1つ以上のグラフトリンカーと、を含む、形成することと、
(B)コアポリマー粒子の分散液(D1)の存在下で、1つ以上のアクリルモノマーに水性乳化重合(B)を行うことと、を含む、方法である。
グラフト%=100×(Wshell0-Wshellsol)/Wshell0
式中、Wshell0は最初の試料中のシェルポリマーの重量であり、WshellsolはTHF中に溶解したシェルポリマーの重量である。
TSO-1=以下の構造を有するテレケリックシリコーンオイル(式中、pが198である)
ALMA=アリルメタクリレート
MMA=メチルメタクリレート
SLS=ラウリル硫酸ナトリウム
NaPS=過硫酸ナトリウム
PVC=ポリ塩化ビニル
pbw=重量部
phr=樹脂100重量部あたりの重量部
99.3重量部のBAおよび0.7重量部のALMAの混合物(M0)を調製した。その後、75重量部のTSO-1および25重量部のBA/ALMA混合物(M0)の混合物(M1)を調製した。混合物(M1)を水およびSLS(M1の重量に基づいて0.5重量%のSLS)と組み合わせた。混合物M1を、キャビテーションの原理に基づいて作動する超音波プロセッサで乳化して、エマルジョンE1を形成した。混合物M1の量は、エマルジョンE1の重量に基づいて25重量%であった。エマルジョンE1を丸底フラスコに移し、t-ブチルヒドロペルオキシド(tBHP)、硫酸第一鉄、およびホルムアルデヒドスルホキシル酸ナトリウム(SFS)のレドックス開始系で重合させた。この系は、72℃で約1時間の半減期を有する油溶性熱開始剤であるTrigonox 125(ペルオキシピバル酸t-アミル)も総モノマーに基づいて1%で含んだ。この段階を45℃に加熱し、約65℃に発熱した。その結果、コアポリマー粒子が分散した。
様々な追加のコア/シェルポリマーを作製した。各々、実施例1と同様であった。様々なテレケリックシリコーン油(TSO)を使用し、全てTSO-1と同じ構造を有し、様々なp値を有した。コアポリマー中の様々な成分の相対量を変化させた。全ての実施例において、BA/ALMA比は、99.3/0.7重量であり、SLSの量は、コア/シェルポリマーの乾燥重量に基づいて、0.5重量%であり、コアポリマーのシェルポリマーに対する重量比は、80/20であった。
これらの実施例は、PVC中の耐衝撃性改良剤としての有効性についても試験した。非可塑化PVCの典型的な配合物を使用し、PVC100重量部あたり4、5、または6phrの乾燥改良剤を使用した。配合物を混合し、その後、加熱したプラスチック加工2ロールミルで粉砕し、次いで、プラークにプレスした。耐衝撃性を、23℃でのノッチ付きアイゾット衝撃試験(ASTM D256、American Society of Testing and Materials,Conshohocken PA,USA)によって試験した。各実施例に対して10個の複製試料を試験した。
比較を等しいphrレベルで使用した改良剤間で行った場合、全ての発明例が比較例よりも良好な耐衝撃性を示すことが明らかである。
実施例2-1および2-2を以下のように試験した。ポリマー粒子の水性分散液を凍結乾燥させて、ポリマー粒子の集合体を固体形態で生成した。固体試料をフィルムにプレスし、表面をAFMによって調査した。いずれの試料も、シリコーンが豊富な相、ポリ(BA)が豊富な相、およびポリ(MMA)が豊富な相の3つの相を示した。実施例2-2では、シリコーンが豊富な相のドメインのサイズは、実施例2-1よりも大きかった。
