Abstract

We present an asymototic analysis of small angle neutron scattering data of a comb-shaped charged copolymer, poly (1-octadecene-co-maleic anhydride), in D20. It is shown that at full ionization, the coRolymer self-asso iate to form cylindrical shape micelles with a radius 26Å and length 101 Å. The number of repeating units per micelle is calculated to be 200 and the hydration number 15 per repeating unit. The dimension of the cylinder remains approximately constant over the concentration range studied.
