PROBLEM TO BE SOLVED: To obtain a curable silicone elastomer composition which can give a cured product reduced in compression set by adding a salt of a cationic organonitrogen compound to a silicone composition suited for the production of a rollable rubber or pumpable liquid injection-moldable composition. SOLUTION: Desirably this composition contains (1) an alkenylorganopolysiloxane and (2) a hydrogen-containing silicon compound selected from the group consisting of hydrogen-containing silanes and hydrogen- containing organopolysiloxanes. The salt of the cationic organonitrogen compound is desirably, for example, a cation of a cycloaliphatic nitrogen-containing heterocyclic ring having the formula: (CH2-e Qe )f NRN<5> g H2-g [wherein e is 0, 1, or 2; Q is a 1-40 monovalent organic group; f is an integer of 4 or greater; RN<5> is a 1-40C monovalent organic group; and g is 0, 1, or 2]. |
