    Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition capable of manifesting a high stiffness, excellent thermal stability, extremely low gel content, etc., by reacting a polymer containing a propylene homopolymer and a propylene copolymer with a compound such as a polyfunctional (meth)acrylic acid derivative. SOLUTION: This composition is obtained by reacting (A) a polymer containing (i) 60-92wt.% propylene homopolymer and (ii) 8-40wt.% propylene copolymer containing 15-70wt.% comonomer of a 2-10C 1-alkene introduced into the polymer chain based on the amount of the copolymer, with (B) a compound of the formula [R is H or a 1-4C alkyl; X is a 1-30C alkyl, etc.; (n) is 2 or 3] at 180-280 deg.C under 1-100 bar pressure within the range of 0.2-10min average retention time of the reaction mixture. The composition has 0.1-100g/10min melt flow index at 230 deg.C under 2.16kg load, and
