dcterms:abstract
  • To estimate the recycling feasibility of high melt indexed polycarbonate, 3.5 inch LGP, tensile, flexural and impact specimens were injecti on molded and the LGP was shredded into sc raps. The scraps were injection molded again and this process was repeated for 4 times. Properties of the sample, i.e., optical properties, mechanical properties and number average molecular weight were measured at each cycle. Based on the results, as the number of reprocessing increased, transmittance decreased at low wavelength and color coordinate was changed systematically to yellow. Yellow index increased more than twofold during 4 recycling processes. On the o ther hand, the number average molecular weight decreased during recycling processes. Flexural and impact strength showed no tendency according to the number of recycling, but tensile strength decreased sharply after the third recycling process. Based on th ese properties, it was concluded that the number of recycling for high melt indexed polycarbonate allowed in this study was one (xsd:string)
