Os modificadores foram utilizados em separado e combinados. Em todos os casos, manteve-se a concentração de modificador fixa em 8% em peso e foram avaliadas as propriedades dos produtos obtidos em função da sua composição. A técnica de polimerização empregada foi a de massa/suspensão. Os melhores resultados foram obtidos para os sistemas PS/modificadores mistos. Os resultados obtidos para estes sistemas comprovam que a copolimerização por enxertia gera produtos com melhores propriedades de impacto do que as obtidas, a partir de misturas mecânicas dos componentes individuais, em sistemas semelhantes.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-21T10:55:50Z No. of bitstreams: 1 a02v08n3.pdf: 165346 bytes, checksum: e55f403b952eb80848a4c8695565baf2 (MD5)Made available in DSpace on 2011-12-21T10:55:50Z (GMT).
