Pei-hua LI, Tao HU, Jing-jin LUO, Xing-hou GONG, Chong-gang WU. Advances in Modification of Mechanical Properties and Heat Resistance of Polystyrene[J]. Polymer Bulletin, 2018,31(7):28-41.
different methods to modify mechanical properties and heat resistance of polystyrene (PS) have systematically been reviewed. These include filling the PS directly or in situ during its polymerization with inorganic fillers
unfunctionalized or functionalized
blending the PS directly or in situ during its polymerization with polymers
unmodified or modified
cross-linkings (ionic cross-linking
interpenetrating polymer network
covalent cross-linking
etc. )
random
graft or block copolymerization starting from monomers
two method coupled modifications (e. g.
blending-filling
copolymerization-blending
copolymerization-filling
ionic crosslinking-blending
and ionic crosslinking- filling)
etc. Based on the above
the advantages and disadvantages have been compared and discussed of various modification methods.
