polystyrene

Limonene needed in recycling foamed polystyrene was extracted from the ear of schizonepeta tenuifolia using ligroin.

Results indicate interestingly that the double bond of GMA polymerized with polystyryl carbanion and the molar ratio of epoxy end group and polystyrene oligomer can be adjusted.

In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.

The reaction between polystyrene having oxazoline groups(RPS) and chlorinated polyethylene(CPE) was investigated by FTIR, DSC methods.
