Based on their versatility with respect to amino acid type and sequence, polypeptides have become attractive for a number of biological applications such as drug delivery, biomineralization, and drugs. N-carboxy anhydride (NCA) polymerization is a convenient way to rapidly prepare high-molecular weight polypeptides with good control over molecular weight and polydispersity. However, the kinetic...

The immune response to the random linear terpolymer of L-glutamic acid, L-lysine, and L-phenylalanine (GLphi) is under dominant H-2-linked Ir gene control in the mouse. Matings between two nonresponder strains produced responder F1 hybrids, demonstrating complementation of the nonresponder alleles. This observation, coupled with the fact that several intra H-2 recombinant strains derived by rec...

This paper is focused on the influence of polystyrene (PS)-poly(1,4-butadiene) (PB)-poly(ethylene oxide) (PEO) triblock terpolymers on the w/o microemulsion of the pseudo-ternary system water/sodium dodecylsulfate (SDS)/xylene-pentanol. Despite the insolubility of the copolymer in water as well as in the xylene-pentanol mixture, it can be incorporated into the w/o microemulsion and interactions...

Heterotelechelic polystyrene (PS), poly(tert-butyl acrylate) (PtBA), and poly (methyl acrylate) (PMA), containing both azide and triisopropylsilyl (TIPS) protected acetylene end groups, were prepared in good control (Mw/Mn 1.24) by atom transfer radical polymerization (ATRP). The end groups were independently applied in two successive ‘‘click’’ reactions, that is: first the azide termini were f...
