Abstract

Use of at least one compound for crystallization of polyester or polyolefin polymers, characterized in that the compound comprises two hydrogen bonding motifs, a linker connecting said hydrogen bonding motifs and side arms R and R' bound to the opposite of the hydrogen binding motifs, wherein each hydrogen bonding motif resides in a molecular plane and wherein the linker between the hydrogen bonding motifs is chosen such that one of the hydrogen bonding motifs resides in a different molecular plane than the other hydrogen bonding motif(s). They work effectively in promoting the crystallization of a range of polymers, and obtained crystallized polymers have a good transparency and retain a high molar mass.
