In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.
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.
While it can technically be recycled, it's not particularly practical, because a truck full of lightweight, air-filled Styrofoam doesn't melt down into a lot of polystyrene.
The Save-a-Cup scheme was set up by the vending and plastics industries to recycle as many as possible of the three-and-a-half billion polystyrene cups used each year.
Organic rafting materials such as trees and root masses have far shorter lives at sea, when compared to synthetic materials such as fiberglass or polystyrene.
It’s collecting all sorts from sort of tiny bits, plastic needles and bits of polystyrene, all the way up to bits of broken bucking plastic bottle as well.”
