BINDER, MATERIALS, AND METHOD FOR PRODUCING MATERIALS
PROBLEM TO BE SOLVED: To provide materials that have high mechanical strength and can be decayed with time.SOLUTION: A binder according to the present invention is for bonding together aggregates in materials having decaying properties. The binder contains aliphatic polyester. For the aliphatic polyester, a weight average molecular weight 1 hour after immersed in an ion exchange water at 80°C ranges from a value of 0.5 or more times larger than a weight average molecular weight before immersion to a value of 0.95 or less times smaller than that.SELECTED DRAWING: None
【課題】高い機械的強度を備え、時間の経過に伴い、崩壊させることができる資材を形成する。【解決手段】結合剤は、崩壊性を有する資材における骨材同士を結合するための結合剤であって、上記結合剤は、脂肪族ポリエステルを含んでなり、上記脂肪族ポリエステルは、８０℃のイオン交換水中に浸漬してから１時間後における重量平均分子量が、浸漬する前の重量平均分子量の０．５以上、０．９５倍以下である。【選択図】なし
