Beschreibung
Zusammenfassung:	The invention relates to a curable benzoxazine macromonomer containing at least 3 benzoxazine rings and at least one aliphatic, heteroaliphatic, araliphatic, heteroaraliphatic, aromatic or heteroaromatic fragment comprising a shortest atom chain containing at least 40 consecutive atoms betwen two benzoxazine nitrogen atoms or between two benzoxazine oxygen atoms, and said atom chain must not include any oxazine ring atoms ('soft fragment'). The invention further relates to cured products made thereof and a method or producing the same. L'invention concerne un macromonomère de benzoxazine pouvant durcir contenant au moins trois anneaux benzoxazines et au moins un fragment aliphatique, hétéroaliphatique, araliphatique, hétéroaraliphatique, aromatique ou hétéroaromatique qui comporte la chaîne d'atomes la plus courte contenant au moins 40 atomes consécutifs entre deux atomes d'azote de benzoxazine ou entre deux atomes d'oxygène de benzoxazine, ladite chaîne d'atomes ne devant pas comprendre d'atomes d'anneau oxazine (« fragment mou »). L'invention concerne en outre des produits durcis obtenus à partir de ces macromonomères et un procédé de fabrication de ces derniers.
