Preface Green Polymer Chemistry is a crucial area of research and product development that continues to grow in its influence over industrial practices. Developments in these areas are driven by environmental concerns, interest in sustainability, desire to decrease our dependence on petroleum, and commercial 1 opportunitiestodevelop“green”products.
