Microphase separated structures based on N-substituted polydiallylamines

Abstract

SUMMARY The ionogenic polymers namely poly(N,N-diallyl-N-cetylammonium hydronitrate) (PDACA HN03) and poly~N,N-diallyl-~,N-~methyl~monium chloride)-bZoc~-poly(cetyl acrylate) (PDADMAC1-block-PA-16) were synthesized via activation of the terminal double bond of the PDADMACl precursor and initiat~on of the polyme~zation 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 -HN03 completely restricts the crystallization of the ionogenic backbones which, however, control the layered structure and the crystallization of the aliphatic chains. In PDADMAC1-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.
