ABSTRACT:
A plastic optical fiber which comprises a core consisting of an amorphous polymer containing a plasticizer and a cladding consisting of a transparent polymer which substantially prevents cross-migration of said plasticizer therein and has a refractive index lower than the core polymer, and which is preferably produced by a process which comprises heat polymerizing a monomer which is polymerized to afford said amorphous polymer and contains said plasticizer, a polymerization initiator and a chain transfer agent, melt spinning said amorphous polymer to form a core and simultaneously cladding the core with said transparent polymer.
