요약서: front page image
(EN)The present invention is directed to a crosslinked or non-croslinked polymer particle, wherein the crosslinked polymer particle comprises a copolymer of poly (alklyene glycol-graft-acrylate) that is crosslinked by at least one hydrolysable monmer or crosslinking agent. The present invention is also directed to a polymer particle comprising a crosslinked polymer particle that is a product of starting materials comprising (a) a hydrophilic monomer, (b) a hydrophobic monomer, and (c) a hydrolysable crosslinking agent (the crosslinking agent may be absent in the case of non-crosslinked particles). The present invention is still further directed to a polymer particle comprising a crosslinked copolymer, where the crosslinked copolymer includes structures represented by Formulas (I), (II), and (III), as defined in the specification. Other embodiments of the present invention also include methods of manufacturing polymer particles.
(FR)La présente invention concerne une particule de polymère réticulé ou non réticulé, la particule de polymère réticulé comprenant un copolymère de poly(alkylène glycol-greffage-lactate) qui est réticulé par au moins un monomère hydrolysable ou un agent de réticulation. La présente invention concerne également une particule de polymère comprenant une particule de polymère réticulé qui est obtenue à partir des composés de départ suivants : (a) un monomère hydrophile, (b) un monomère hydrophobe et (c) un agent de réticulation hydrolysable (l'agent de réticulation peut être absent dans le cas des particules non réticulées). En outre, la présente invention concerne une particule de polymère comprenant un copolymère réticulé contenant les structures représentées par les formules (I), (II) et (III) qui sont définies dans la mémoire. Dans d'autres modes de réalisation, la présente invention concerne des procédés de préparation de particule de polymère.
