(wherein R.sub.1 to R.sub.3 represent a substituent having a carbon number of 1 to 12, and R.sub.4 and R.sub.5 represent an alkyl group having a carbon number of 1 to 12).

The present invention relates to a method for obtaining a monomer by degrading a polymer, the polymer being a homo or copolymer of the monomer, the method comprising the steps of providing the polymer and a solvent as a reaction mixture in a reactor, wherein the solvent is a reactant capable of reacting with the polymer to degrade the polymer into oligomers and at least one monomer; providing a reusable catalyst being capable of degrading the polymer into oligomers and at least one monomer; degrading the polymer in the reaction mixture at reaction conditions using the catalyst to form a monomer; and recovering the catalyst from the reaction mixture; wherein the method further comprises the addition of a base to at least one of the reaction steps. The present invention furthermore relates to the use of a base as a co-catalyst for a catalyst for degrading a polymer in a reaction mixture at reaction conditions.

A bamboo charcoal powder-based false eyelash is obtained by evenly mixing 90-96% of polyester particles, 3-8% of bamboo charcoal powder and 1-2% of adjuvant, subsequently hot melting, wire drawing and forming and then cooling. The false eyelash can be subjected to not only chemical sharpening tip but also physical sharpening tip, has greatly reduced weight and is environmental-friendly; an organosilicon quaternary ammonium salt structure and three chlorine atoms in the adjuvant synergistically take antibacterial effects, and a long carbon chain further enhances an antibacterial effect. The adjuvant promotes the dispersion of the bamboo charcoal powder which promotes the compatibility and combination of the adjuvant and a matrix resin, their combined action improves the antibacterial property of the false eyelashes, and therefore the prepared false eyelash has good antibacterial and anti-inflammatory effects, can well protect skins around eyes from being damaged by external environment, and has both aesthetics and high safety.
