| 摘要 |
<p>The present invention relates to core-shell particles comprising comprising :
- a core consisting essentially of at least one tetrafluoroethylene (TFE) polymer [polymer (F)], said core having an average primary particle size of less than 50 nm; and
- a shell consisting essentially of at least one acrylic polymer [polymer (A)], said polymer (A) comprising recurring units, more than 50 % by moles of said recurring units being derived from at least one ethylenically unsaturated monomer having directly bonded to one of the sp 2 carbon atoms of the ethylenic unsaturation at least one group of formula:
wherein Z is a group selected among -OR', wherein R' can be a hydrogen atom or a C 1-10 hydrocarbon group; and -NR"R"', wherein R" and R"', equal or different each other, can be independently a hydrogen atom or a C 1-10 hydrocarbon group [hereinafter, acrylic monomer (AM)].
Still objects of the invention are a process for manufacturing said core-shell particles, their use as ingredients/additives in polymer compositions, polymer composition and articles comprising the same.</p> |
