使用されたPTTは、1.02dl/gの固有粘度を有するSORONAブライトポリ(トリメチレンテレフタレート)(E.I.du Pont de Nemours and Company,Wilmington,DE)であった。
ポリ(トリメチレンテレフタレート)およびPAHAの固有粘度(IV)は、ASTMD5225−92に基づく自動化方法に従って19℃において0.4グラム/dL濃度において50/50重量%トリフルオロ酢酸/塩化メチレンに溶解されたポリマーについて、Viscotek Forced Flow Viscometer Y900 (Viscotek Corporation,Houston,TX)で測定された粘度を用いて定量された。PTTによって測定されたIV値は、ASTMD4603−96に従って60/40重量%のフェノール/1,1,2,2−テトラクロロエタン中で手動で測定されたIV値に相関された。米国特許第5840957号明細書も参照のこと。
成形物の物理的性質は、Instron Corp.引張試験機のモデル番号1125(Instron Corp.,Norwood,MA)を用いて試験バーを用いて測定された。
全て重量によってPTT/PLAポリマー組成物5%(実施例1)、10%(実施例2)、および20%(実施例3)を含有するポリマー組成物(ポリマー組成物の残余はPTTであった)を用いて、PTTとPLAとの混合物を調製し、配合および押出し、ペレット化し、引張バーに成形した。比較例AはPLAが添加されていないPTTであり、対照標準として用いられ、従ってブレンディングを省いた。性質は表1および2に記載される。
ガラス充填成形製品を実施例1〜3および比較例Aのポリマー組成物を用いて作製した。ガラス繊維の量を表2に示されるように変えた。結果を以下に示す。
(a)PTTの重量に基づいたガラス繊維の%。ガラス繊維はPittsburgh Plate Glass Company(Pittsburgh PA)から入手可能な#3563である。
