Resinas modificadas y usos de las mismas

Se proporcionan resinas termoplásticas de hidrocarburos termoplásticos modificados, así como métodos para su fabricación y usos de las mismas en composiciones de caucho. Las resinas termoplásticas modificadas se modifican disminuyendo la cantidad relativa de oligómeros dímero, trímero, tetrámero y pentámero en comparación con los polímeros de resina termoplástica no modificados correspondientes, lo que da como resultado un producto que exhibe un mayor cambio en la temperatura de transición vítrea del elastómero (s) utilizado en formulaciones de neumáticos. Esto se traduce en mejores predictores viscoelásticos del rendimiento de la banda de rodadura de los neumáticos, como el agarre en mojado y la resistencia a la rodadura. Las resinas termoplásticas modificadas confieren propiedades notables a diversas composiciones de caucho, tales como neumáticos, correas, mangueras, frenos y similares. Se ha demostrado que los neumáticos de automóviles que incorporan resinas termoplásticas modificadas poseen excelentes resultados en el equilibrio de las propiedades de resistencia a la rodadura, desgaste de los neumáticos, rendimiento en nieve y rendimiento de frenado en mojado.
