Abstract | The present invention relates to a composition comprising a polymer P1 comprising monomer units derived from vinylidene fluoride and a polymer P2 comprising monomer units derived from a monomer M2 of formula R1R2C=C(R3)C(O)R in which the substituents R1, R2 and R3 are, independently of each other, selected from the group consisting of H and C1-C5 alkyl; R is selected from the group consisting of -NHC(CH3)2CH2C(O)CH3 or -OR' with R' selected from the group consisting of C1-C18 alkyl optionally substituted by one or more -OH group(s) or a five-or six-membered heterocycle comprising at least one nitrogen atom in its cyclic chain, characterised in that the difference between the melting temperature and the crystallisation temperature of the composition is greater than or equal to 40°C and in that the composition is in powder form.
La présente invention concerne une composition comprenant un polymère P1 comprenant des motifs monomériques issus du fluorure de vinylidène et un polymère P2 comprenant des motifs monomériques issus d'un monomère M2 de formule R1R2C=C(R3)C(O)R dans laquelle les substituants R1, R2 et R3 sont indépendamment les uns des autres sélectionnés parmi le groupe consistant en H et C1-C5 alkyle; R est sélectionné parmi le groupe consistant en -NHC(CH3)2CH2C(O)CH3 ou -OR' avec R' sélectionné parmi le groupe consistant en C1-C18 alkyle optionnellement substitué par un ou plusieurs groupement(s) -OH ou un hétérocycle à cinq ou six chainons comprenant au moins un atome d'azote dans sa chaine cyclique, caractérisée en ce que la différence entre la température de fusion et la température de cristallisation de ladite composition est supérieure ou égale à 40°C et en ce que ladite composition est sous la forme d'une poudre. |
