Crystallinity and Stereoregularity of Polybutene-1
Kobunshi Kagaku, 1962 X線回折による結晶化度と密度とを主としてZieglem触媒により合成したポリブテン-1について測定した。結晶化度と比容積との間に直線関係が成立することから, 結晶質と非晶質の密度の値0.950および0, 868が得られた。アイソタクチックポリブテン-1には結晶化バンドとみなしうる吸収が多数見出された。一方, 1221cm-1バンドは固態状態ではその吸光度比の値が比容積と直線関係を示すが溶融状態や溶液で消失しない。したがって固態状態で一定の熱処理をした試料について比較するときには結晶化度の尺度として使用しうると考えられる。吸光度比 (A1221/A1151) と密度 (d) との間には次の実験式が成立する。

Journal of Vinyl and Additive Technology, EarlyView.A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3
The FEBS Journal, EarlyView.Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their
