摘要： The present invention relates to polystyrylpyridine-type resins having increased toughness, and composite materials containing these resins.The resin of the invention contains a polycondensation product of at least two reactive methylated substituents, the said resin having the following general formula (I): U.sub.x V.sub.y W.sub.z in which: ##STR1## U denotes the grouping ##STR2## V denotes the grouping ##STR3## W denotes the grouping in which:R, R.sub.1 are identical or different and denote a chain segment consisting of hydrocarbon radicals and able to contain hetero atoms,A, A.sub.1 are identical or different and denote an atom or group forming a bridge between the segment R and an aromatic nucleus of the styrylpyridine chain, containing stereomobile bonds,R.sub.2 denotes hydrogen, or a methyl or ethyl radical, x, y, z denote integers that may be equal to 0, the sum y+z being at least equal to 1.Advantageously, A, A.sub.1 denotes an oxygen atom. The resins of the invention have better mechanical properties than conventional polystyrylpyridine (PSP) resins, particularly at ambient temperature, yet preserve the excellent thermostability and moisture resistance properties characteristic of PSP resins. This resin may be used as matrix in a laminate.
