Title (EN) PARTICLES WITH RADIAL VARIATION
(FR) PARTICULES À VARIATION RADIALE
Abstract:
(EN) A polymeric bead having radius R wherein the polymer comprises 0.3% to 20% by weight, based on the weight of the polymer, of polymerized units of one or more multifunctional vinyl monomer and 80% to 99.7% by weight, based on the weight of the polymer, of polymerized units of one or more monofunctional vinyl monomer, (a) wherein the polymerized units of multifunctional vinyl monomer have radial distribution factor MR of 0.9 to 1.1, and (b) wherein some of the vinyl groups in the polymerized units of multivinyl monomer are unreacted, and the unreacted vinyl groups have a radial distribution factor VR of 2.5 or higher.
(FR) La présente invention concerne une bille polymère possédant un rayon R, le polymère comprenant de 0,3 % à 20 % en poids, sur la base du poids du polymère, d'unités polymérisées d'un ou de plusieurs monomères vinyliques multifonctionnels et de 80 % à 99,7 % en poids, sur la base du poids du polymère, d'unités polymérisées d'un ou de plusieurs monomères vinyliques monofonctionnels. Selon l'invention : (a) les unités polymérisées de monomère vinylique multifonctionnel présentent un facteur de distribution radiale MR de 0,9 à 1,1, et (b) certains des groupes vinyle dans les unités polymérisées de monomère polyvinylique n'ont pas réagi, et les groupes vinyle n'ayant pas réagi présentent un facteur de distribution radial VR de 2,5 ou plus.
