Description
α,β−不飽和酸のグリシジルエステルユニットは、例えばアクリル酸グリシジルエステル、メタクリル酸グリシジルエステル、エタクリル酸グリシジルエステル、イタコン酸グリシジルエステル等であるが、特にメタクリル酸グリシジルエステルが好ましい。
製造例1(全芳香族ポリエステル液晶樹脂(成分(A) )の合成)
p−ヒドロキシ安息香酸345重量部(73モル%)、6−ヒドロキシ−2−ナフトエ酸175重量部(27モル%)、酢酸カリウム0.02重量部、無水酢酸350重量部を、攪拌機及び留出管を備えた反応器に仕込み、十分に窒素置換した後、常圧下で150℃まで温度を上げ、攪拌を開始した。150℃で30分攪拌し、更に徐々に温度を上昇させ、副生する酢酸を留去した。温度が300℃に達したところで、徐々に反応器を減圧し、5Torr(即ち665Pa)の圧力で1時間攪拌を続け、目標の攪拌トルクに達した時点で、反応器下部の排出孔を開け、窒素圧を使って樹脂をストランド状に取り出した。排出されたストランドをペレタイザーにより粒子状にした。この全芳香族ポリエステル液晶樹脂の融点は280℃、300℃での溶融粘度は50.1Pa・sであった。

実施例1〜5、比較例1〜3
上記(A) 、(B) 成分を表1に示す割合で二軸押出機((株)日本製鋼所製TEX30α型)を用いてシリンダー温度300℃にて溶融混練し、樹脂組成物のペレットを得て、射出成形に供し、評価した。試験片としては、ファナック社製Roboshot α−100iA成形機を用い、シリンダー温度300℃、金型温度80℃の条件で0.7mm厚の平板を成形した。
[溶融粘度]
キャピラリー式レオメーター(東洋精機製キャピログラフ1B:ピストン径10mm)により、温度T1(樹脂の融点+20℃)、剪断速度1000sec-1の条件での見掛けの溶融粘度をISO 11443に準拠して測定した。測定には、内径1mm、長さ20mmのオリフィスを用いた。
[コア層厚み]
0.7mm厚の平板について、偏光顕微鏡写真観察により成形品全厚みに対するコア層厚みの比率(%)を評価した。
[打ち抜き試験]
オリエンテック製テンシロンUTA-50kN試験機で0.7mm厚の平板試験片を用いて打ち抜き試験を行った。先端直径16mmの半球状打ち抜き治具を用い、試験速度100mm/minで試験を行った。
[落錘試験]
固定した平板試験片中央部に、図3に示す先端が半球状(球直径;9mm)の治具をのせ、この治具の上に任意の重さの重錘を任意の高さから落下させ、試験片が破壊するかを確認した。
結果を表1に示す。
