  • FUNCTIONALIZED POLYMERS
    Publication number: 20230312791
    Abstract: A functionalized polymer contains monomeric units of general formula (I) In general formula (I), R1 is selected from alkyl radicals and alkenyl radicals, which may be branched or straight chained, and unsubstituted or substituted: and R2 is selected from H and methyl. The monomeric units of general formula (I) make up for at least 90 wt.-% of the total weight of the polymer. The polymer has a polydispersity index PDI of 4.5 to 20. A process for can be used producing the functionalized polymers. The functionalized polymers are useful, especially in the field of personal care.
