PS Polystyrenes

Ref. 136. LDPE = low density polyethylene HDPE = high density polyethylene PP = polypropylene PS = polystyrene EPVC = flexible PVC ... 

Fig. 11. Effect of polyolefin primers on bond strength of ethyl cyanoacrylate to plastics. All assemblies tested in accordance with ASTM D 4501 (block shear method). ETFE = ethylene tetrafluoroethylene copolymer LDPE = low-density polyethylene PFA = polyper-fluoroalkoxycthylene PBT = polybutylene terephthalate, PMP = polymethylpentene PPS = polyphenylene sulfide PP = polypropylene PS = polystyrene PTFE = polytetrafluoroethylene PU = polyurethane. From ref. [73].

Polystyrene (PS). Polystyrene is available in a range of grades which generally vary in impact strength from brittle to very tough. The non-pigmented...

PS polystyrene Si02 silica aFe203 hematite. The superscripts + and indicate the sign of the charge on the sorbent particles. 

FIGURE 5.2 Synthesis of a peptide on a solid support according to Merrifield in 1964. PS = polystyrene. Initially, the protector was benzyloxycarbonyl, removed by HBr in CHjCOjH, followed by final deprotection with the same reagent at 78°C. The current protocol employs CF3C02H and HF, respectively.
