Goodyear discovered a way of introducing sulfur versions of these structures in natural rubber, which allows rubber to stretch but not tear.
"Type IIb (two B) metal-enmeshed polymers are defined by metals that create these structures. The Flory-Rehner equation can be used to calculate the density of these structures from swelling experiments. After exposing a photo•resist to light, one does a hard•bake to allow these structures to be created. These structures can exist on the three "ortho" and "para" positions in phenol, which is why phenol•ic resins are almost entirely connected by them. PEX, or XLPE, is a polymer that is named for the presence of these structures. Charles (*) Goodyear discovered a way of introducing sulfur versions of these structures in natural rubber, which allows rubber to stretch but not tear. For 10 points, name these bridges that occur between polymer chains, as exemplified by disulfide bonds.
