Summary
A series of novel amphiphilic networks were synthesized by free-radical mediated copolymerization/crosslinking of N,N-dimethyl acrylamide (DMAAm) with various molecular weight octa-methacrylate telechelic polyisobutylene stars (PIB(MA)8) as crosslinking agents. The overall composition of the PDMAAm-l-PIB(MA)8 networks were controlled by controlling the concentration of the starting materials. Crosslinking was essentially complete as indicated by negligible sol fractions in both methanol and n-hexane. Swelling ratios and swelling rates of various PDMAAm-l-PIB(MA)8 in water and n-heptane were determined and contrasted with those of networks prepared with di- and tri-methacrylate-telechelic PIB croslinkers (PIB(MA)2 and PIB(MA)3). The mechanical properties of water-swollen tubules made of PDMAAm-l-PIB(MA)8 were studied and compared with tubules made with PIB(MA)2 and PIB(MA)3.
