采用差热扫描分析、红外光谱、固体核磁、小角X光散射等方法研究了聚(β-羟基丁酸酯-co-β-羟基戊酸酯(P(HB-co-HV))/聚(对-羟基苯乙烯)(简称PVPh)共混物的相容性和形态.结果表明两组分间形成较强的分子间氢键,形成完全相容的共混体系.固体核磁结果表明P(HB-co-HV)/PVPh(50/50)在3.4nm尺寸上是完全均相的.小角X光散射结果表明,在等温结晶的共混物中无定形的PVPh分子分散在P(HB-co-HV)片晶之间与非晶的P(HB-co-HV)分子形成非晶区,从而使非晶区加宽,长周期增加
The effects of poly (β-hydroxybutyrate-co-β-hydroxyvalerate (P (HB-co-HV)) / poly P-hydroxystyrene (PVPh) blends.The results showed that the two components formed strong intermolecular hydrogen bonds to form a completely compatible blends.The solid state NMR results showed that P ( HB-co-HV) / PVPh (50/50) is completely homogeneous at 3.4 nm.The results of small-angle X-ray scattering show that amorphous PVPh molecules are dispersed in the P -co-HV) lamellae form amorphous regions with amorphous P (HB-co-HV) molecules, thereby widening the amorphous region and increasing the long period
