  • Vinyl monomers capable of forming side-chain liquid crystalline polymers and the resulting polymers
    Patent number: 4613658
    Abstract: There is disclosed a new vinyl monomer capable of forming polymeric vesicles, micelles, monolayers, and side-chain liquid crystalline polymers. The vinyl monomer is of the formula ##STR1## wherein R.sub.1 is substituted or unsubstituted long chain alkyl or aryl and R.sub.2 is a hydrogen atom, alkyl, or aryl.The side-chain liquid crystalline polymers can be formed by free radical polymerization or by anionic polymerizations techniques. The different reaction methods give polymers of different configuration; the anionic technique results in a polymer having a nitrogen atom in the backbone. The polymers are useful in film and fiber formation and display good toughness.
