The SML/NJ Library is a collection of libraries that are distributed with SML/NJ. Due to differences between SML/NJ and MLton, these libraries will not work out-of-the box with MLton.
As of 20180119, MLton includes a port of the SML/NJ Library synchronized with SML/NJ version 110.82.
You can import a sub-library of the SML/NJ Library into an MLB file with:

This will automatically convert a $/smlnj-lib.cm import in an input .cm file into a $(SML_LIB)/smlnj-lib/Util/smlnj-lib.mlb import in the output .mlb file.
The following changes were made to the SML/NJ Library, in addition to deriving the .mlb files from the .cm files:
HTML4/pp-init.sml (added): Implements structure PrettyPrint using the SML/NJ PP Library. This implementation is taken from the SML/NJ compiler source, since the SML/NJ HTML4 Library used the structure PrettyPrint provided by the SML/NJ compiler itself.
Util/base64.sml (modified): Rewrote use of Unsafe.CharVector.create and Unsafe.CharVector.update; MLton assumes that vectors are immutable.
Util/graph-scc-fn.sml (modified): Rewrote use of where structure specification.
Util/redblack-map-fn.sml (modified): Rewrote use of where structure specification.
Util/redblack-set-fn.sml (modified): Rewrote use of where structure specification.
Util/time-limit.mlb (added): Exports structure TimeLimit, which is not exported by smlnj-lib.mlb. Since MLton is very conservative in the presence of threads and signals, program performance may be adversely affected by unnecessarily including structure TimeLimit.
Util/time-limit.mlton.sml (added): Implements structure TimeLimit using structure Engine. The SML/NJ implementation of structure TimeLimit uses SML/NJ’s first-class continuations, signals, and interval timer.
