Vegetable oils polymer based

IPNs are formed sequentially by more than one IPN in a process, whereas simultaneous IPNs are formed simultaneously. However, semi-IPNs are formed by the polymerisation of a monomer in the presence of a polymer. All the types of IPN listed earlier are found in vegetable oil-based polymers. These IPNs have some advantages over polymer blends or cross-linked polymers. 

Polymers obtained from natural products or from their immediate derivatives such as vegetable oil, modified epoxidised oils, transesterified oils, heated oil, monoglyceride and diethanol amide or fatty acids of vegetable oils, cashew nut seed liquid (CNSL) and derivatised polymers, are bioderived polymers. " The details of vegetable oil-based polymers are the subject matter of this book and hence are discussed in detail in subsequent chapters.

It is environmentally important to perform a life cycle assessment analysis, not only for non-biodegradable polymers but also for partially biodegradable or even completely biodegradable polymers. Life cycle analysis (LCA) is a tool which helps in understanding the environmental impact associated with the products, processes and activities throughout the life of a polymer. The life cycle of vegetable oil-based polymers is shown in Rg. 2.6. Thus a complete LCA would include three separate but interrelated components, an inventory analysis, an impact analysis and an improvement analysis.
