Resumo: The present work focuses on the synthesis of diblock copolymers of the type polyester-block-poly(acrylate) by one-pot methodology, by combining the polymerization techniques ROP and SET-LRP. The proposed strategy was based on the use of a heterofunctional initiator that has functional groups capable of initiating polymerizations by both mechanisms in only two stages of synthesis, in the same reaction vessel and without the need for prior purification between stages. In the study, the effects of the presence of ROP catalyst, solvent type and monomer structure on the polymerization kinetics of the SET-LRP step and the copolymer quality were evaluated. By optimizing the synthesis conditions, copolymers with low dispersity and well controlled molar mass were obtained.

A estratégia proposta foi baseada no uso de um iniciador heterofuncional que possui grupos funcionais capazes de iniciar as polimerizações por ambos mecanismos em apenas duas etapas de síntese, no mesmo recipiente reacional e sem a necessidade de purificação prévia entre uma etapa e outra. No estudo, foram avaliados os efeitos da presença do catalisador ROP, tipo de solvente e estrutura do monômero na cinética da polimerização da etapa SET-LRP e na qualidade dos copolímero obtidos. Através da otimização das condições de síntese, foram obtidos copolímeros com baixa polidispersão e bom controle de massa molar.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em QuímicaUFSMBrasilQuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessSET-LRPROPOne-potCopolímero diblocoIniciador heterofuncionalDiblock copolymerHeterofunctional initiatorCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICAMétodos simplificados de síntese de copolímeros através da combinação das técnicas SET-LRP e ROPSimplified methods for the synthesis of copolymers by combination of the SET-LRP and ROP techniquesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisGiacomelli, Cristianohttp://lattes.cnpq.br/1429116139250396Silveira, Nádya Pesce dahttp://lattes.cnpq.br/7383039987082609Lopes, Poliana Pollizellohttp://lattes.cnpq.br/3168039205334003http://lattes.cnpq.br/5907927139233224Trindade, Suelen Gauna10060000000060041f37587-ea61-4b16-a6ef-406dce2bea70bcde53e3-96e5-41d3-9aa7-480dd2440ccb2612da61-41e3-459f-aed9-2bb26b370538cc577c45-44cc-4579-b76a-73834eb6ee67reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGQUIMICA_2017_TRINDADE_SUELEN.pdfDIS_PPGQUIMICA_2017_TRINDADE_SUELEN.pdfDissertação de Mestradoapplication/pdf2888950http://repositorio.ufsm.br/bitstream/1/17995/1/DIS_PPGQUIMICA_2017_TRINDADE_SUELEN.pdfb1fd43791b1e10f192a2b646f6af1958MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
