    • The invention aims at providing core/shell type nanoparticles which have high heat resistance and shape retentivity and contain as the core nanoparticles having specific particle diameters which were difficult of production. Such core/shell type nanoparticles can be produced by preparing aromatic nanoparticles through the polymerization of an aromatic compound such as trialkoxybenzene with an aldehyde, surface-modifying the nanoparticles with reactive functional groups, and introducing graft chains to the resulting nanoparticles by graft polymerization with the reactive functional groups used as the initiator or the terminator through ring-opening polymerization, vinyl polymerization or addition polymerization. For example, bromomethyl is used as the reactive functional group and the graft polymerization is conducted by ring-opening polymerization of oxazoline, or ARTP polymerization of acrylic acid derivatives, styrene, or the like with the bromomethyl used as the initiator. Thus, core/shell type nanoparticles wherein the aromatic nanoparticle constitutes the core and the graft chain constitutes the shell can be obtained.
    • 本发明旨在提供具有高耐热性和形状保持性的核/壳型纳米颗粒,并且包含具有难以生产的特定粒径的核心纳米颗粒。 这种核/壳型纳米颗粒可以通过通过芳族化合物如三烷氧基苯与醛的聚合制备芳族纳米颗粒来制备,用反应性官能团对纳米颗粒进行表面改性,并通过接枝聚合将引入接枝链 通过开环聚合用作引发剂或终止剂的反应性官能团,乙烯基聚合或加成聚合。 例如,使用溴甲基作为反应性官能团,通过恶唑啉的开环聚合或丙烯酸衍生物,苯乙烯等的ARTP聚合与作为引发剂的溴甲基进行接枝聚合。 因此,可以获得其中芳族纳米颗粒构成核并且接枝链构成壳的核/壳型纳米颗粒。

    • A process for producing a modified phenolic resin which comprises heating and stirring a heavy oil or pitch together with a formaldehyde compound and a phenol represented by the formula (I) (wherein R is a C2-10, linear or branched, unsaturated hydrocarbon group having one or two unsaturated bonds; p is 1 or 2; X is C1-5 alkyl; and q is 0 or 1) in the presence of an acid catalyst to conduct polycondensation, the amounts of the formaldehyde compound and the phenol being 0.3 to 25 mol in terms of formaldehyde amount and 0.5 to 50 mol, respectively, per mol of the heavy oil or pitch. The modified phenol obtained by the process has flowability around room temperature because it has a far lower melting point than conventional modified phenolic resins obtained from a heavy oil or pitch. It further has a low melt viscosity and hence excellent moldability. When used in combination with an epoxy resin, the modified phenol can give a molded article excellent not only in heat resistance, moisture resistance, corrosion resistance, adhesion, etc. but also in dimensional stability and mechanical properties including strength.
    • 一种改性酚醛树脂的制造方法,其特征在于,将重油或沥青与甲醛化合物和式(I)表示的苯酚(其中R 1为C2-10,直链或支链,不饱和的) 具有一个或两个不饱和键的烃基; p为1或2; X为C 1-5烷基; q为0或1)在酸催化剂存在下进行缩聚,甲醛化合物和苯酚的量为 相对于每摩尔重油或沥青,甲醛量分别为0.3〜25摩尔和0.5〜50摩尔。 通过该方法获得的改性苯酚在室温下具有流动性,因为它具有比从重油或沥青得到的常规改性酚醛树脂低得多的熔点。 它还具有低熔体粘度,因此具有优异的成型性。 当与环氧树脂组合使用时,改性酚可以得到不仅在耐热性,耐湿性,耐腐蚀性,粘附性等方面优异的成型品,而且还具有包括强度在内的尺寸稳定性和机械性能。
