Depolymerization and self-disassembly of plant polymers

Biopolymers can be radiolytically degraded mainly in two ways. The first way, depolymerization, occurs at not so high temperatures and consists in random cleavage of bridges between monomer units. The second process, self-disassembly, ...  read more
