Abstract: front page image
(EN)Provided is a polymer modifying agent composition which provides a modified polymer that exhibits excellent low heat generation properties when formed into a vulcanized product. The polymer modifying agent composition modifies a polymer having a carbon-carbon unsaturated bond, and contains (A) a nitrone having at least one carboxy group and (B) a fatty acid having 6 or more carbon atoms.
(FR)Cette invention concerne une composition d'agent de modification de polymère qui permet d'obtenir un polymère modifié présentant d'excellentes propriétés de faible génération de chaleur quand il est converti en un produit vulcanisé. La composition d'agent de modification de polymère modifie un polymère ayant une liaison insaturée carbone-carbone, et contient (A) une nitrone ayant au moins un groupe carboxy et (B) un acide gras ayant 6 atomes de carbone ou plus.
(JA) 加硫物にしたときの低発熱性に優れる変性ポリマーを与えるポリマー変性剤組成物を提供する。上記ポリマー変性剤組成物は、炭素-炭素不飽和結合を有するポリマーを変性させるポリマー変性剤組成物であって、少なくとも1個のカルボキシ基を有するニトロン(A)と、炭素数6以上の脂肪酸(B)と、を含有する。
