项目摘要
A series of polyesters was synthesized by the bulk polycondensations of the combinations of 1,4 : 3,6-dianhydrohexitols with aliphatic dicarboxylic acid derivatives and with difuranic diesters, i.e., bis (5-methoxycarbonyl)-2-furyl) methane and 1,1-bis(5-methoxycarbonyl)-2-furyl) ethane. To prepare furan-containing polyesters, the polycondensations were carried out at 220-230゚Cin the presence of titanium isopropoxide as a catalyst, giving polyesters haveing number average molecular weight up to 2.4*10^4. Soil burial tests along with enzymatic degradation experiments showed that these polyesters are potentially biodegradable.Soil burial degradation behavior of miscible blend systems of poly (vinyl alcohol) (PVA)/chitin-graft-poly (2-methyl-1-oxazoline) and PVA/chitin-graft-poly (2-ethyl-2-oxazoline) was investigated in comparison with the case of a pure PVA film. The degradation of the hybrid films was followed by the weight changes, scanning electron microscopic (SEM) observation, FT-IR,^1H NMR,and SEC analyzes. The rate of degradation of the PVA/chitin derivative hybrids was faster than that of pure PVA in the soil burial test.
以1,4,3,6 -二氢己醇与脂肪族二羧酸衍生物和二呋喃二酯(即双(5-甲氧基羰基)-2-呋喃基)甲烷和1,1-双(5-甲氧基)-2-呋喃基)乙烷为原料,通过缩聚反应合成了一系列聚酯。以异丙醇钛为催化剂,在220 ~ 230‰的温度下进行缩聚反应,制得数平均分子量达2.4*10^4的含呋喃聚酯。土壤掩埋试验和酶降解实验表明,这些聚酯具有潜在的可生物降解性。研究了聚乙烯醇(PVA)/几丁质接枝-聚(2-甲基-1-恶唑啉)和聚乙烯醇/几丁质接枝-聚(2-乙基-2-恶唑啉)混相共混体系的土壤埋藏降解行为,并与纯PVA膜进行了比较。通过质量变化、扫描电镜(SEM)观察、傅里叶变换红外光谱(FT-IR)、核磁共振谱(^1H NMR)和SEC分析等方法研究了杂化膜的降解过程。在土壤掩埋试验中,PVA/几丁质衍生物杂交种的降解速度比纯PVA快。
