The ionogenic polymers namely poly( N , N ‐diallyl‐ N ‐cetylammonium hydronitrate) (PDACA · HNO 3 ) and poly( N , N ‐diallyl‐ N , N ‐dimethylammonium chloride)‐ block ‐poly(cetyl acrylate) (PDADMACl‐ block ‐PA‐16) were synthesized via activation of the terminal double bond of the PDADMACl precursor and initiation of the polymerization of the acrylic monomer in alcohol solution. The microphase separated structure of a blend of both homopolymers and of the block copolymer was proved by differential scanning calorimetry (DSC) and X‐ray diffraction measurements. Side chain crystallization in PDA‐CA · HNO 3 completely restricts the crystallization of the ionogenic backbones which, however, control the layered structure and the crystallization of the aliphatic chains. In PDADMACl‐ block ‐PA‐16 crystalline polyacrylate blocks coexist with crystalline ionogenic blocks. The length of the polyacrylate block influences the ability of the ionogenic block to form the crystalline structure.
