Biotechnology and Polymers Most Chemically Synthesized Polymers are not Biodegradable, such as PE, PP, PS and PET While most Biologically Synthesized Polymers are Biodegradable, such as Proteins, Cellulose, Glycan The most Notable Biopolymers with Properties Similar to Thermoplastics are: Polyhydroxyalkanoates or PHA

第一节硫、磷原子的成键特征 1.由于价电子层构型类似,所以硫、磷原子可以形成与氧、氢相类似的共价键化合物。 2.由于3P轨道比2P轨道比较扩散,它与碳原子的2P轨道的相互重叠不如2P轨道之间那样有效,以硫、磷原子难以和碳原子形成稳定的PPπ键
