A commercially available titanate coupling agent, LICA 12 from Kenrich Petrochemicals was used to study its eAect on talc filled polypropylene. It was found that the melt viscosity of the filled PP decreased and dispersion quality was improved in the presence of coupling agent. Further investigation on molecular weight distribution (MWD) shows that polypropylene (PP) molecules have undergone some chain scission and coupling reactions resulting in a broader MWD. Glass transition temperature (Tg… CONTINUE READING
