sults obtained by investigations carried out of four vulcanized
producto are dealt with, each of which is oo:ijposfd of two
kinds of rubber. Thoue vulcanized producto tihow vuriout3 forma
of microinhomogeneity and size. From the boundaries of these
microinhomogeneities conclusions may be drawn as to compatabi-
lity In that a diffuse boundary indicate3 better compatibility.
There are 3 figures and 9 references, 6 of Nhich are Soviet.

ABSTRACT: The .-.olorinetric method for evaluat'n the dispersity of
carbon black was discussed in Part I Nef 1). This"article
describes investigations on the Istruc,;urel of carbon
blac'-t. After defining the terminology of Icarbott blacl',Z
partLclesl, cry3tallite, and the primary and secondary
aggr,igate~ methods for the quantitative evaluation of the
fundamental 'structure' of carbon black are discu3-;ed.
None of these methods was entirely satisfactory. Com-
1;ara,;ive evaluation of the fundamental 'structure' can be
achieved by defining the oil number and the 13tructurel
