反応器内で、α-ナフトールアラルキル樹脂(SN495V、OH基当量:236g/eq.、新日鐵化学(株)製:ナフトールアラルキルの繰り返し単位数nは1~5のものが含まれる。)0.47モル(OH基換算)を、クロロホルム500mlに溶解させ、この溶液にトリエチルアミン0.7モルを添加した。温度を-10℃に保ちながら反応器内に0.93モルの塩化シアンのクロロホルム溶液300gを1.5時間かけて滴下し、滴下終了後、30分撹拌した。その後さらに、0.1モルのトリエチルアミンとクロロホルム30gの混合溶液を反応器内に滴下し、30分撹拌して反応を完結させた。副生したトリエチルアミンの塩酸塩を反応液から濾別した後、得られた濾液を0.1N塩酸500mlで洗浄した後、水500mlでの洗浄を4回繰り返した。これを硫酸ナトリウムにより乾燥した後、75℃でエバポレートし、さらに90℃で減圧脱気することにより、褐色固形の上記一般式(1)で表されるα-ナフトールアラルキル型シアン酸エステル化合物(式中のRはすべて水素原子である。)を得た。得られたα-ナフトールアラルキル型シアン酸エステル化合物を赤外吸収スペクトルにより分析したところ、2264cm-1付近にシアン酸エステル基の吸収が確認された。
合成例1で得たα-ナフトールアラルキル型シアン酸エステル化合物40質量部と、ビス(3-エチル-5-メチル-4-マレイミドフェニル)メタン(BMI-70、ケイ・アイ化成(株)製)20質量部と、ビフェニルアラルキル型エポキシ樹脂(NC-3000-FH,日本化薬(株)製)40質量部と、シランカップリング剤(Z6040、東レダウコーニング(株)製)5質量部と、酸基を含む湿潤分散剤(BYK-W903、ビッグケミー・ジャパン(株)製)5質量部とをメチルエチルケトンで溶解混合し、これに、平均粒子径3μmのベーマイト(BMT33W、河合石灰(株)製)240質量部と、平均粒子径0.3μmの球状アルミナ(ASFP-20、電気化学工業(株)製)60質量部と、モリブデン酸亜鉛(日本無機化学工業(株)製)3質量部と、ニッカオクチックスマンガン(Mn8%)(日本合成化学工業(株)製)0.01質量部、2,4,5-トリフェニルイミダゾール(東京化成工業(株)製)0.5質量部とを混合して、樹脂ワニスを得た。なお、平均粒子径(D50)は、各々の無機充填材をメチルエチルケトンで分散させ、その後超音波ホモジナイザーにて3分間分散処置を行なった後、レーザ回折散乱式の粒度分布測定装置((株)島津製作所製)を用いて測定した値である。得られた樹脂ワニスをさらにメチルエチルケトンで希釈し、これを質量47.2g/m2のEガラスクロス(旭化成イーマテリアルズ(株)製)に含浸塗工し、160℃で3分間加熱乾燥することにより、0.1mmmtで樹脂含有量84質量%のプリプレグを得た。次に、得られたプリプレグを2枚重ね合わせ、得られた積層体の上下面に12μm厚の電解銅箔(3EC-III、三井金属鉱業(株)製)を配置し、圧力30kgf/cm2及び温度220℃で120分間の真空プレスを行い積層成形することで、厚さ0.2mmの金属箔張り積層板(両面銅張積層板)を作製した。また、得られたプリプレグを8枚重ね合わせること以外は同様に行い、厚さ0.8mmの金属箔張り積層板(両面銅張積層板)を作製した。
1)外観評価:厚さ0.2mmの金属箔張り積層板を330mm×330mmのサイズに切断後、両面の銅箔をすべてエッチング除去して、表面の銅箔がすべて除去されたサンプル(積層板)を得た。この積層板を目視で観察し、ボイドが発生していないものを「○」、ボイドが発生したものを「×」と評価した。
2)熱伝導率:厚さ0.8mmの金属箔張り積層板の密度を測定し、また、比熱をDSC(TA Instrumen Q100型)により測定し、さらに、キセノンフラッシュアナライザ(Bruker:LFA447 Nanoflash)により熱拡散率を測定した。そして、熱伝導率を以下の式から算出した。
熱伝導率(W/m・K)=密度(kg/m3)×比熱(kJ/kg・K)×熱拡散率(m2/S)×1000
4)ドリルビットライフ(ドリルビット折損孔数):下記のドリル孔加工条件にて5000hit加工後、3セット重ね合わせた金属箔張り積層板の最下板の裏面を、ホールアナライザ(日立ビアメカニクス製)にて測定し、統計孔数をカウントした(表1に示す数値は、加工2回(n=2)の平均値である。)。
