Abstract: A hair gel-NVV polymer was synthesized from N-vinylpyrrolidone (NVP), vinyl versatate (VeoVa10) and vinyl acetate (VA) under the action of azobisisobutyronitrile (AIBN). NVV was characterized by ATR-FTIR and 1HNMR. The influence of the amount of NVP on the properties of the resin, the curl retention of the NVV polymer used in the hair gel, and the carding performance were analyzed. The results show that when n(NVP): n(VA): n(VeoVa10) was 2:1:1, the styling performance of NVV polymer was improved by 50% compared with polyvinylpyrrolidone (PVP), and the carding performance was improved by 100%. NVV resin is natural and long-lasting, has good affinity with hair, is not easy to be wetted by moisture, and can form a uniform smooth coating on the hair. So it is suitable for hair styling products.
