-
Page/Page column 66, (2017/06/02)
A resin composition which comprises polylactic acid, does not release an isocyanate group at the time of production and has excellent hydrolysis resistance and a low environmental burden. The resin composition comprises: (A) 100 parts by weight of a resin component (component A) containing polylactic acid (component A-α);(B) 0.001 to 10 parts by weight of a compound (component B) having one carbodiimide group and a cyclic structure in which first nitrogen and second nitrogen are bonded to each other via a bonding group, the cyclic structure consisting of 8 to 50 atoms; and(C) 0.001 to 2 parts by weight of at least one antioxidant (component C) selected from the group consisting of a hindered phenol-based compound, a phosphite-based compound, a phosphonite-based compound and a thioether-based compound.

Page/Page column 15-16, (2011/10/19)
A cyclic carbodiimide compound which is useful as an end-sealing agent for polymer compounds. The cyclic carbodiimide compound is represented by the following formula (i): In the above formula, X is a divalent group or a tetravalent group represented by the following formula (i-4). When X is divalent, q is 0 and when X is tetravalent, q is 1. Ar1 to Ar4 are each independently an aromatic group. They may be substituted by an alkyl group having 1 to 6 carbon atoms or phenyl group.
