    摘要: An acrylic elastomer composition containing: 100 parts by mass of an acrylic elastomer; and 2 to 15 parts by mass of at least one of a plasticizer represented by the chemical formula (1):

    wherein R 1 , R 2 , R 3 , and R 4 each represent an alkyl group having 4 to 18 carbon atoms, and R 1 , R 2 , R 3 , and R 4 may be the same alkyl group or may be different from each other, and wherein the acrylic elastomer contains 0.1 to 5 parts by mass of a crosslinking monomer unit with respect to 100 parts by mass of an acrylic acid alkyl ester unit.

    摘要: An object of the invention is to provide a submicron-order scaly boron nitride fine particle having a low major diameter/thickness (aspect) ratio, high purity and high crystallinity.
    The invention provides a boron nitride fine particle, characterized by having an average particle diameter of 0.05 to 2.0 µm, a graphitization index of 3 or less, and a total oxygen content of 0.20% by mass or less, with an average value of a major diameter/thickness ratio of scaly particles being 6.0 or less, and a method of producing a boron nitride fine particle, characterized by introducing ammonia and an alkoxide borate at an ammonia/alkoxide borate molar ratio of 1 to 5 in a reaction vessel in an inert gas atmosphere for heating at 800 to 1,350°C within 30 seconds thereby obtaining a boron nitride precursor, and then heating the boron nitride precursor at 1,650 to 2,200°C for at least 0.5 hour in an inert gas atmosphere.
