A subset A of a poset P is a q-anti&in if it can be obtained as the union of at most q antichains. A ranked poset P is said to be q-Sperner if the maximum number of elements of a q-antichain of P is the sum of the cardinalities of its q larger rank-sets. P is strongly Spernu if it is q-Sperner for a

## Abstract Three polyester films with different repeating unitsβ€”poly(lactic acid) (PLA), poly(ethylene terephthalate) (PET), and poly(oxybenzoate‐__co__‐oxynaphthoate) (PBN)β€”were modified by plasma, and the way in which the chemical compositions of the polymer chains influenced the plasma modifica
