Sir the concept of plasticizers and crosslinking is opposite in the sense one keeps the chain separated and the other crosslink between the chain, however, both positively contribute to polymers. How is it possible?
Brittleness is not simply correlated with amorphous structure. Yes, ordinary soda-lime-silica glass is amorphous and brittle. But most ceramics, say SiC for example, are crystalline and brittle. And metallic glass is ductile despite being amorphous.
@Vishal Dolas I think temperature must play a role. However, structure of silica glass cannot be described in terms of chains as in the case of polymers.
