Cross-linkable polymer compositions of an olefinic polymer modified by an unsaturated silane bearing hydrolyzable groups and a zeolite, wherein the zeolite is an adduct of a zeolite in finely divided form having a water content not higher than 3% by weight modified at a temperature of at least 150.degree. C. with at least one carboxylic and/or sulfonic organic acid.

Cross-linkable polymeric compositions, process for their preparation and

Nucleants for thermodegradable crystalline polyolefines made up of zeolitic molecular sieves modified with at least one arylcarboxylic acid. These nucleants may be added before or during the macroradicalic degradation of the polyolefines and allow products having a high degree of nucleation to be obtained.

Zeolitic nucleants for crystalline polyolefines modified by means of

Self-extinguishing polymeric compositions are taught comprising, expressed in % by weight referrred to the total composition:
