  • Polymeric substrates with attached thiocarbonylthio-containing groups
    Patent number: 11390722
    Abstract: First articles with covalently attached thiocarbonylthio-containing groups are provided. More specifically, the first articles are a functionalized substrate that contains a solid polymeric substrate with a plurality of thiocarbonylthio-containing groups covalently attached directly to carbon atoms in a polymeric backbone of the solid polymeric substrate. Methods of making the first articles with covalently attached thiocarbonylthio-containing groups are provided. Additionally, second articles and methods of using the first articles to generate second articles with covalently attached polymeric chains are provided.
    Type: Grant
