目前有许多生物可降解聚合物正在使用。保利(ε-caprolactone) (PCL)发现的脂肪族聚酯被发现是有用的假肢,缝合,也在许多的药物交付(半圆和Hutmacher 2010)。这种化合物的IUPAC名称是(1,7)-聚异氰酸酯-2- 1。这些化合物的其他名称是2-羟基戊烷homo聚合物和6-己内酯聚合物(Labet和Thielemans 2009)。这个化合物的CAS号是24980-41-4。这个化合物的常用缩写是PCL。化合物的密度是1.145克/厘米^ 3。这种化合物的熔点是60摄氏度。它们被发现存在于25摄氏度的标准状态下。这种化合物在20世纪70年代和80年代很有名,但在当今时代已经被发现(Sugih et al. 2009)。由于这些化合物在生物材料上的应用(Agarwal, Wendorff,和Greiner 2009),它最近在当今时代得到了重视。它们被发现是相对便宜的产品,具有适合特定解剖部位的可降解动力学(Mas et al. 2008)。这使得这种化合物具有可行性和广泛的用途。流变学发现该化合物作为生物材料具有广泛的用途(Hutmacher et al. 2001)。流变学研究是对物质在液体或软状态下流动的研究。塑性流动是基于对外加力响应的弹性而发生变形的(Eshraghi和Das 2010)。当与挤出的淀粉反应时,发现化合物的流变行为是显著的(Eshraghi和Das 2010)。当在离线毛细管流变仪(Young et al. 2004)中观察到这种情况时,发现化合物的电源线模型具有适当的校正因子。淀粉的稠度系数K明显较高(Yu et al. 2006)。淀粉-PCL纳米复合材料共混物具有剪切细化行为(Mavis et al. 2009),其伪塑性高于100% PCL。发现化合物的粘度高于PCL复合材料(Zhang et al. 2009)。

There are a number of biodegradable polymers that are in use in the current times. Poly (ε-caprolactone) (PCL) is found to be an aliphatic polyester which has been found to be useful in the prosthetic, suture and also in many of the drug deliveries (Woodruff and Hutmacher 2010). The IUPAC name for the compound is (1,7)-polyocepan-2-one. The other names for the compounds are 2-oxepenane homo polymer and 6-Caprolactone polymer (Labet and Thielemans 2009). The CAS number for this compound is 24980-41-4. The common abbreviation for the compound is PCL. The density of the compound is 1.145 g/Cm^3. The melting point of the compound is 60 Degree Celsius. They are found to exist at the standard state of 25 Degree Celsius. This compound was famous in the 1970s and 1980s but it has been found the compounds in the current times (Sugih et al. 2009). It has recently gained prominence in the current times owing to the biomaterial applications of these compounds (Agarwal, Wendorff, and Greiner 2009). They have been found to be relatively inexpensive products that are found to have degradable kinetics to suit specific anatomical sites (Más et al. 2008). This makes this compound feasible and widely in use. Rheology of the compound is found to have wide variety of uses as biomaterial (Hutmacher et al. 2001). The rheological study is the study of the flow of the mater in the liquid or the soft state. The plastic flow is found to be deforming based on the elasticity in the response to the applied force (Eshraghi and Das 2010). The rheological behavior of the compounds was found to be pronounced when reacted with the extruded starch (Eshraghi and Das 2010). This was found to be the case when observed in the off-line capillary rheometer (Young et al. 2004) The power line model for the compounds was found to have appropriate correction factors. The consistency coefficient K for the starch was found to be significantly higher ( Yu et al. 2006). The Starch-PCL Nano composite blends were found to have shear-thinning behavior (Mavis et al. 2009) This was found to have higher pseudo plasticity than did 100% PCL. The viscosity of the compounds was found to be higher than the PCL composite ( Zhang et al. 2009) .

These are some of the notable features of the PCL. These components have been used for number of commercial applications. There is a need to synthesize the compounds to convert it into compounds that are viable. These have been explained in the subsequent section.
