The research activity implemented in the present book was focused on polymeric materials based on polyolefins that are the predominant polymers mostly used for consumer packaging. Attempts were made to develop several ecocompatible blends and composites utilizing polyolefins in conjunction with other biodegradable polymeric materials. Much attention was focused on novel ecocompatible materials based on blends of polyhydroxybutyrate (PHB) and polystyrene (PS). Additionally, a new strategy was planned to compatibilize PS-PHB based blends through the synthesis of an A-B copolymer from PHB by...
