Description
(A)ポリブチレンテレフタレート系樹脂
ポリブチレンテレフタレート系樹脂(A)とは、テレフタル酸成分(テレフタル酸又はそのエステル形成誘導体)、及び炭素数4のアルキレングリコール(1,4−ブタンジオール)又はそのエステル形成誘導体を少なくとも重合成分とする熱可塑性樹脂である。
ポリエステルエラストマー(熱可塑性ポリエステルエラストマー、ポリエステル型エラストマー)は、ハードセグメント(又は硬質成分又は硬質ブロック)およびソフトセグメント(又は軟質成分又は軟質ブロック)のうち少なくとも一方がポリエステル成分で構成されていればよいが、通常、ハードセグメントとして硬質ポリエステルブロック(例えば、ポリアルキレンアリレートブロックなどの芳香族ポリエステルブロック)を含むブロック共重合体であってもよい。
本発明の特色は、PBT系樹脂と環状ポリエステルオリゴマーとを組み合わせる点にある。通常、PBT系樹脂に流動性改良剤などを添加すると、流動性を向上できても、PBT系樹脂そのものが有する機械的強度などの特性の低下を避けることができない。本発明では、環状ポリエステルオリゴマーを使用することにより、前記特性を高いレベルで保持しつつPBT系樹脂組成物の流動性を効率よく向上できる。また、ポリエステルエラストマーと組み合わせることにより、樹脂組成物又はその成形品の靱性を向上でき、このような靱性の向上効果もまた、ポリエステルエラストマーの使用によっても低下することがないため、靱性と機械的強度の保持と、流動性の向上とをバランスよく両立させることができる。
上記式において、アルキレン基Rとしては、例えば、エチレン基、プロピレン基、トリメチレン基、テトラメチレン基、ヘキサメチレン基などのC2−12アルキレン基(特に直鎖状C2−12アルキレン基)、好ましくはC2−8アルキレン基、さらに好ましくはC2−4アルキレン基などが挙げられる。また、上記式において、二価の脂環式基Rとしては、シクロアルキレン基R(例えば、1,4−シクロヘキシレン基などのC5−10シクロアルキレン基)、シクロアルカンジアルキレン基(例えば、1,4−シクロヘキサンジメチレン基などのC5−10シクロアルカン−ジC1−4アルキレン基など)などが挙げられる。また、nは、1以上であればよく、例えば、1〜10、好ましくは1〜5、さらに好ましくは1〜3、特に1であってもよい。なお、nが2以上であるとき、複数のRは同一又は異なるアルキレン基又はシクロアルキレン基で構成してもよい。
本発明の樹脂組成物は、前記のように溶融流動性に優れているため、成形加工性が良好であり、機械的強度や耐熱性の高い成形体又は成形品を製造するのに有用である。
表に示す混合比率で各成分を、ドライブレンドし、30mmφのスクリューを有する2軸押出機((株)日本製鋼製)を用いて、250℃で溶融混練したのちペレット化した。得られたペレットを用いて、表に示す各評価を行った。結果を表に示す。
(A−1)ポリブチレンテレフタレート(固有粘度IV=0.69dL/g、ウィンテックポリマー(株)製)
(A−2)ポリブチレンテレフタレート(固有粘度IV=0.875dL/g、ウィンテックポリマー(株)製)
(B)ポリエステルエラストマー;
(B−1)「ペルプレンS2002」(東洋紡(株)製)
(B−2)「ペルプレンGP300」(東洋紡(株)製)
(C)環状ポリエステルオリゴマー;
環状ポリブチレンテレフタレートオリゴマー(サイクリクスコーポレイション社製、「CBT」(Cyclie butyleneterephthalate)、融点140〜190℃)
(D)充填剤;
ガラス繊維(日本電気硝子(株)製、「ECSO3T187」)。
キャピログラフ1B((株)東洋精機製作所製)を用いて、得られたペレットを140℃で3時間乾燥後、炉体温度260℃、キャピラリーφ1mm×20mmLにて、剪断速度1000sec−1にて測定した。溶融粘度数値が低いほど流動性に優れる。
得られたペレットを140℃で3時間乾燥後、成形温度260℃、金型温度80℃で、射出成形を行った。射出成形により得たISO3167引張試験片について、ISO527−1、2に定められている評価基準に従い評価した。なお、伸びが80%を超えるものについては「>80」と示した。
