Abstract

Currently 35 % of the total carpet production is composed by scraps and leftovers from the manufacturing process, which are incinerated or disposed of in landfills. In this context, the production of multi-stimuli response copolymers that improve the redispersilbe of polymeric film and subsequent reuse of carpet fibers are of great industrial and academic interest. The objective of this research project is to synthesize copolymers with multi-stimulus responsive for carpet production, in order to reuse of fibers and polymeric nanoparticles for production of new materials. The polymeric nanoparticles will be obtained by emulsion polymerization of monomers: styrene (Sty), n-butyl acrylate (ABu) and ethylene glycol dimethacrylate (EGDMA). In the present project, the stabilizer will be carried out to obtain the polymer nanoparticles with stimulus response by solution copolymerization of methacrylic acid with N,N-diethylaminoethyl methacrylate (DEAEMA). The polymeric nanoparticles will be characterized and used for the production of carpets, which will be evaluated in accordance with the stability of the pieces and redispersibility of the polymeric film and reuse of these fibers and nanoparticles. This project is integrated with FAPESP number 2013/25619-3 and it will be developed in partnership with BASF and ICT-UNIFESP polymer group for carpet production and characterization.
