Abstract
Description
で表されるメタクリル酸エステル由来の単位を構成単位とする親水性ポリマーアームAと、下記式(2)
で表されるメタクリル酸エステル由来の単位を構成単位とする疎水性ポリマーアームBを同一分子内に有する星型ポリマーを含む摩擦低減用コーティング組成物を提供する。
本開示において、摩擦低減用コーティング組成物は、前記式(1)(式中、R1は、ポリ(アルキレングリコール)若しくはポリ(アルキレングリコール)アルキルエーテルの化学構造式の1つのヒドロキシル基から水素原子を除いた基、又はヒドロキシアルキルオキシ基を示す)で表されるメタクリル酸エステル由来の単位を構成単位とする親水性ポリマーアームAと、前記式(2)(式中、R2は、炭素数1〜18のアルキル基を示す)で表されるメタクリル酸エステル由来の単位を構成単位とする疎水性ポリマーアームBを同一分子内に有する星型ポリマーを含む。
アルゴン雰囲気下、ナス型フラスコに、トリメチルシリロキシエチルメタクリレート(TMSOEMA)(360mmol、78.5mL)、メチル 2−クロロ−2−フェニルアセテート(MCPA)(3.6mmol、0.548mL)、クロロ(インデニル)ビス(トリフェニルホスフィン)ルテニウム(II)(ジクロロメタン付加物)(0.24mmol、207mg)、トリブチルアミン(2.4mmol、0.572mL)をトルエン160mLに溶解し、10分間アルゴンでバブリングした。80℃で48h反応させた後、氷冷して反応を停止した。反応液をエバポレーション後、メタノールに溶解させ、水を加えることでリニアポリマー(PTMSOEMA)を沈殿精製した。
SEC(サイズ排除クロマトグラフィー)(THF):Mn=22,300、Mw/Mn=1.40、Mn(NMR)=22,400
アルゴン雰囲気下、ナス型フラスコに、メチルメタクリレート(MMA)(300mmol、31.8mL)、エチル 2−クロロ−2−フェニルアセテート(ECPA)(3.0mmol、0.514mL)、クロロ(インデニル)ビス(トリフェニルホスフィン)ルテニウム(II)(ジクロロメタン付加物)(0.20mmol、172mg)、トリブチルアミン(2.0mmol、0.476mL)をトルエン167mLに溶解し、10分間アルゴンでバブリングした。80℃で72h反応させた後、氷冷して反応を停止した。反応液を大量のヘキサンに滴下し、沈殿精製することでリニアポリマー(PMMA)を得た。
SEC(THF):Mn=10,700、Mw/Mn=1.36、Mn(NMR)=8,800
アルゴン雰囲気下、シュレンク管に、クロロ(インデニル)ビス(トリフェニルホスフィン)ルテニウム(II)(ジクロロメタン付加物)とトリブチルアミンのトルエン溶液をあらかじめ調製しておき、最終濃度が以下に示す濃度になるように反応容器であるナス型フラスコに加えた。
アルゴン雰囲気下、ナス型フラスコに、製造例1で得られたポリマー(PTMSOEMA)(0.169g/mL トルエン溶液、1.88mmol、249mL)、製造例2で得られたポリマー(PMMA)(0.625mmol、5.5g)、エチレングリコールジメタクリレート(25mmol、4.72mL)、トリメトキシベンゼン(1.5mmol、250mg)、クロロ(インデニル)ビス(トリフェニルホスフィン)ルテニウム(II)(ジクロロメタン付加物)(0.25mmol、215mg)、トリブチルアミン(2.5mmol、0.25mL)をトルエン197mLに溶解し、10分間アルゴンでバブリングした。80℃で72h反応させた後、氷冷して反応を停止した。反応液をトルエンで2倍量に希釈し、シリカゲルカラム及びアルミナカラムにより金属触媒、助触媒を除去した。得られた溶液をエバポレーションし、再度約10重量%のトルエン溶液を調製し、ヘキサンを滴下し、沈殿精製することで、PTMSOEMA/PMMA星型ポリマーを得た。このポリマーを減圧乾燥後、エタノールに溶解させ、12M塩酸を5,6滴加え、一晩撹拌した。反応溶液に大量のヘキサンを加えて沈殿精製することにより、PHEMA/PMMAヘテロ星型ポリマーを得た。星型ポリマー中のPHEMA鎖とPMMA鎖の比を1H NMRにより求めたところ、前者:後者(モル比)=73:27であった。
SEC(DMF):Mn=164,000、Mw/Mn=2.63
実施例3で得られたPHEMA/PMMAヘテロ星型ポリマーをメタノールに溶解して、星型ポリマー1重量%のメタノール溶液を調製した。このメタノール溶液を、バーコータ♯20で、PETフィルム(商品名「コスモシャインA4300 75μ」、東洋紡株式会社製)上に塗布し、乾燥させて測定試料(S1)とした(乾燥後のコート膜の膜厚:0.5μm)。
上記測定試料の上に、水、又は流動パラフィンを塗布し(塗布量:約0.05g/100mm2)、摩擦係数測定装置(商品名「Nano Tribometer」、Anton Parr社製)を用い、下記の条件で測定試料表面の摩擦係数を測定した。結果を図1に示す。図1の右から2つめが、測定試料(S1)上に流動パラフィンを塗布した場合のデータ、右から1つめが、測定試料(S1)上に水を塗布した場合のデータである。
