NUCLEATION EFFECT INHIBITOR, CRYSTALLINE RESIN COMPOSITION AND METHOD OF CONTROLLING CRYSTALLIZATION OF CRYSTALLINE RESIN COMPOSITION

摘要

A nucleation effect inhibitor comprising a compound being any of compounds having at least one structure selected from among polycyclic structures obtained through condensation cyclization of three or more 4- or more-membered cyclic structures, the compounds not including nigrosin, aniline black and copper phthalocyanine derivatives; a crystalline resin composition comprising the nucleation effect inhibitor; and a method of controlling crystallization by the use of the nucleation effect inhibitor.
