    摘要: The present invention relates to diamondoids and diamondoids derivatives as nucleating agents in the manufacture of thermoplastics. The use of diamondoids and diamondoid derivatives as nucleating agents can increase the overall rate of crystallization of thermoplastics and may lead to a reduction of cycle-time in molding processes and generally to increased output as well. Further, performance characteristics, such as, for example, clarity, stiffness, impact properties, hardness, and heat resistance, may be improved in thermoplastic articles formed from thermoplastics containing diamondoids as nucleating agents.
