Research on the preparation of doped polystyrene

One way to diagnose the target conditions during a laserdriven capsule implosion is to incorporate diagnostic dopant atoms in the capsule wall material-polystyrene (PS). In this paper two kinds of doping methods（chemical and physical） are discussed. conventionally,chemical synthesis route to produce polystyrene like polymers is possible.It is straightforward to covalently bond nonmetal dopants like bromine，iodine or other halogens onto plystyrene's pendant rings.Deuterated polystyrene with silicon dopant can also be produced. Metals,on the other hand,do not routinely be bonded covalently to nonmetallic atomic structures.Iron, chromium or titanium，however, can form a stable sandwich compound with a pair of cyclopentadienyl rings.As for the low producing rate and crosslinking of the
