Source sentences:
text: Different catalysts are used to make polymers that possess different properties, with varying sizes of molecules, and in chains that may be linear, branched, or cross-linked.
text: If instead, the chains of rubber molecules are slightly cross-linked by sulfur atoms, a process called vulcanization which was discovered by Charles Goodyear in 1839, the desirable elastomeric properties of rubber are substantially improved.
text: Another arrangement occurs when the long chains are chemically linked together, forming a mesh-like structure known as a crosslinked configuration.
text: Crosslinking means that different chains of polymer molecules have all been linked together, so that the object can uniformly stretch but always returns to its pre-stretching arrangement.
