Biodegradable polymers as biomaterials
Journal of Biomaterials Science, Polymer Edition, 1995Biomaterials are used in prostheses and medical devices for different purposes. Polymers are the most diverse class of biomaterials. All biomaterials must meet certain criteria and regulatory requirements before they can be qualified for use in medical applications. Biocompatibility is one of the most important requirements. Both nondegradable polymers

Journal on Materials and its Characterization
The growing environmental concerns associated with conventional petroleum-based plastics, coupled with rising oil prices and waste-disposal challenges, have accelerated interest in biodegradable polymers. These materials, derived from either renewable natural resources or non-renewable petroleum feedstocks, offer a sustainable alternative to ...

An Overview of Biodegradable Polymers and Biodegradation of Polymers
2002It is now widely recognized that, along with the importance of synthetic polymers possessing long-term stability, there is also a need for polymers that break down in a controlled manner. Biodegradable macromolecules can be tailored specifically for controlled degradation under the inherent environmental stress in biological systems either unaided or ...

The increasing environmental pollution is causing dramatic changes in the ecosystem. The search for solutions to this problem includes the development of new materials using more sustainable resources and processes, the development of biodegradable materials and the use of natural additives to tune the biodegradability of these materials.

Potential alternative to petrochemical polymers, soy protein isolate (SPI), a plentily available, natural biopolymer is chemically modified with thiourea at 2.5, 5, 7.5, 10, 15 and 20 mass/mass% for better processing of plastic as a raw material. From the FTIR studies, it has been ascertained that there is no bonding reaction between SPI and thiourea ...

This chapter considers some of the factors which must be taken into account in the design of biodegradable delivery systems. It reviews the literature on polymer biodegradation in vivo, with emphasis placed on polyesters and results obtained in the authors’ laboratories. Polymers which function by virtue of slow dissolution in the body are not strictly
