Polystyrene grafted onto cellulose

Polystyrene treated with Ar plasma (with Petri dishes as substrates) was also grafted with cellulose derivative polymers [22], then mouse melanoma cells (B16, C3, FIO) were spread onto the treated surfaces. All three cell lines proliferated significantly more slowly after 48 h [23]. Further, we showed that cells aggregated on this modified substrate could rapidly establish gap junctions for communication between the fibronectin of cell membranes and exogenic surfaces [24]. Cell differentiation occurs and can be used in the biological analysis. For example (Fig. 12.3), pyramidal aggregates of melanoma cells (Swiss 3T3) appear on polystyrene substrates coated with cellulose derivatives after 24 h. These... [Pg.184]

Thiohydroxamic esters have also seen applicadon in grafting of polyacrylonitrile onto polyethylene, of polystyrene (PSt), polyacrylamide (PAM), and poly(N-isopropylacrylamide) onto cellulose,and of PS, PMMA, poly(vinyl pyridine), and polyacrylamide onto poly(arylene ether sulfone). The process involves derivatization of a parent carboxy-fimctional polymer to form the thiohydroxamic ester 59 with R= polymer, which then behaves as a polymeric transfer agent. [Pg.193]
