Several contributions have been reported on the preparation of blends and composites based on biodegradable synthetic polymers such as poly(vinyl alcohol) (PVA) and poly(ε-caprolactone) (PCL) with starch., cellulose., and protein materials.. Starch gives substantially immiscible blends with PVA.

Polymeric materials started to be applied in agricultural practices from the sixty’s, mostly in replacing glass as greenhouses and tunnels covering. Thus plastics made possible the introduction of mulching films, a novel agriculture technology not appl

They become hydrophilic as they are degraded by hydrolytic and oxidative processes and their biocompatibility improves with the degradation. It is commonly observed that polymer systems with hydrophilic surfaces which become ‘soft’ when swollen with wate

Just some minutes after mixing, the paste attains high viscosity and must then be injected into the bone cavity, where the final stages of polymerization will take place. The solid is in most cases constituted by poly(methyl metha

Do Biopolymers Fulfill Our Expectations Concerning Environmental Benefits?This book chapter discusses results from Life Cycle Assessment (LCA) studies for the commercially most important biopolymers. Biopolymers are defined here as polymers that are fully or partially produced from renewable raw materials, covering both biodegradable and non-degradable polymers.
