  To provide a method for making a high-refractive-index resin having superior properties such as transparency, hue, heat resistance, impact resistance, and the like. A composition for making a high-refractive-index resin contains a polythiol compound and a compound containing at least two iso(thio)cyanato groups, the polythiol compound having a dithioacetal, dithioketal, orthotrithioformic ester, or orthotetrathiocarbonic ester skeleton. The molar ratio of the mercapto group to the iso(thio)cyanato group in the composition is greater than 1.0 but not more than 3.0. A method for making a resin by curing the composition, a resin prepared by curing the composition, an optical element made from the resin, and a lens made from the optical element are also provided.

  A production process of a propylene block copolymer, comprising the step (I) of polymerizing propylene alone or a combination of propylene with an olefin other than propylene, in the presence of a defined polymerization catalyst, to form a polymer component (1), and the step (II) of copolymerizing propylene with an olefin other than propylene in the presence of the polymer component (1), to form a polymer component (2), wherein a combination of a transition metal compound such as Zr(OR 1 ) 4 and Hf(OR 1 ) 4 (R 1 being a hydrocarbon group) with an ether group-containing linear hydrocarbon compound and/or a Lewis base compound is added to the above polymerization system between the ending point of the step (I) and the starting point of the step (II), or during the step (II).
