Abstract in another language

We report the discovery of a family of org. compds., substituted 1,3,5-benzene trisamides, that - depending on subtle details of their chem. structure- are capable of selectively and extremely efficiently nucleating the growth of the common a-crystal modification of the major industrial polymer isotactic polypropylene (i-PP); rendering this normally turbid material highly transparent ("clarified") at exceedingly low concns. (as low as a wt. fraction of 0.0002); inducing the mech. distinct, tough i-PP b-polymorph; or promoting growth of hybrids of both
crystallog. modifications with heretofore unknown combinations of the above desirable optical-mech. properties. In addn., these trisamide-based compds. exhibit excellent thermal stability and organoleptic neutrality, and do not feature absorption of visible light,
adding to a most favorable set of characteristics that provides marked benefits over presently employed nucleating/clarifying agents. It is anticipated that the present study advances the development of multi-functional additives for tailoring physico-chem. properties also
of other polymers.
