  • Flowability Improver for Engineering Plastics Thermoplastic Resin Compositions Containing the Same and Molded Articles of the Compositions
    申请人:Nabeshima Yasuhiko
    公开号:US20070213451A1
    公开(公告)日:2007-09-13
    A flowability improver for engineering plastics which consists of a polymer (A) composed of 0.5 to 99.5% by mass of aromatic vinyl monomer units (a1), 0.5 to 99.5% by mass of (substituted) phenyl (meth)acrylate monomer units (a2), and 0 to 40% by mass of other monomer units (a3) (with the proviso that the total of the units (a1) to (a3) is 100% by mass) and having a weight-average molecular weight of 5000 to 15000. The flowability improver can improve engineering plastics in melt-flow characteristics (processability in molding) and chemical resistance without impairing the plastics in heat resistance, exfoliation resistance, transparency, and so on.
    这是一种用于工程塑料的流动性改进剂,由聚合物(A)组成,其由0.5至99.5%的芳香族乙烯单体单元(a1)、0.5至99.5%的(取代)苯基(甲基)丙烯酸酯单体单元(a2)和0至40%的其他单体单元(a3)组成(前提是单元(a1)至(a3)的总质量为100%),其重均分子量为5000至15000。该流动性改进剂可以提高工程塑料的熔融流动性(成型过程中的加工性能)和化学耐性,而不会影响塑料的耐热性、剥离性、透明度等性能。
  • Absolute rate constants for hydrocarbon autoxidation. XVI. Reactions of peroxy radicals at low temperatures
    作者:K. Adamic、J. A. Howard、K. U. Ingold
    DOI:10.1139/v69-634
    日期:1969.10.15

    The equilibrium constants for the formation of some t-alkyl tetroxides and the rate constants for irreversible decay of the tetroxides have been measured by electron spin resonance spectroscopy at low temperatures. The equilibrium constant appears to be virtually independent of the nature of the alkyl groups. It is concluded that differences in the rate of constants for chain termination by t-peroxy radicals at ambient temperatures are due chiefly to the differences in rate constants for irreversible tetroxide decomposition. The activation parameters for this reaction indicate that it occurs by one bond rather than two bond scission.

    在低温下,利用电子自旋共振光谱法测量了一些t-烷基四氧化物的形成平衡常数和四氧化物不可逆分解的速率常数。平衡常数似乎与烷基团的性质基本无关。结论是,在常温下,t-过氧自由基链终止的速率常数差异主要是由于不可逆四氧化物分解的速率常数差异。该反应的活化参数表明它是通过一次键裂解而非两次键裂解发生的。
