    篇名/題名:Unusual thermal degradation of maleic anhydride grafted polyethylene
    摘要:Thermal degradation of maleic anhydride grafted polyethylene
    (manPE) in nitrogen and in air was studied by
    thermogravimetry and differential scanning calorimetry.
    The decomposition temperature of manPE in nitrogen
    shifted to a higher value with increasing heating rate,
    but a complex thermal phenomenon was observed
    when manPE decomposed in air. Chain scission and
    crosslinking are proposed as two counteractive factors
    to determine the decomposition temperature in air.
    Radical species (R) and hydroxyl groups (ROH) form
    when manPE degraded in air. The radical species
    accelerate the oxidative degradation, but ROH could
    react with the maleic anhydride groups to form a stable
    crosslinking structure. Both slow heating and prolong
    heating at 2208C allow the stabilizing reaction to
    proceed to a higher degree between ROH and the maleic
    anhydride groups and lead to enhanced thermal
    stability of manPE
