2. The additive masterbatch composition of claim 1 wherein the (A) semi-crystalline polyolefin carrier resin consists essentially of: (i) a semi-crystalline medium density polyethylene; (ii) a semi-crystalline high density polyethylene; (iii) a semi-crystalline polypropylene; (iv) a semi-crystalline ethylene/propylene copolymer; (v) a semi-crystalline poly(ethylene-co-alpha-olefin) copolymer; (vi) a combination (e.g., mixture or blend) of any two or more of (i), (ii) and (v); (vii) the (A) semi-crystalline polyolefin carrier resin has a crystallinity of 50 to < 100 wt%; or (viii) any one of limitations (i) to (vi) and the (A) semi-crystalline polyolefin carrier resin has a crystallinity of 50 to < 100 wt%.

3. The additive masterbatch composition of claim 1 or 2 wherein the (A) semi-crystalline polyolefin carrier resin has (i) a density of at least 0.925 g/cm^ and is a polyethylene or a density of 0.89 to 0.90 g/cm^ and is a polypropylene; (ii) a crystallinity of at least 50 wt% and is a polyethylene; (iii) a melt flow index (MFI) of 0.1 to 20 grams per 10 minutes (g/10 min.) at 190° C./2.16 kg load and is a polyethylene or a melt flow rate (MFR) of 0.5 to 50 g/10 min. at 230 C./2.16 kg load and is a polypropylene; (iv) a molecular weight distribution (MWD) that is monomodal; (v) a MWD that is bimodal; (vi) both (i) and (ii); (vii) both (i) and (iii); (viii) both (ii) and (iii); (ix) both (iv) and at least one of (i) to (iii); or (x) both (v) and at least one of (i) to (iii)

4. The additive masterbatch composition of any one of claims 1 to 3 wherein the (B) acidic condensation catalyst is (i) an organosulfonic acid, an organophosphonic acid, or a hydrogen halide; (ii) an organosulfonic acid; (iii) an alkyl-substituted arylsulfonic acid; (iv) an alkyl-substituted arylsulfonic acid wherein there is/are 1 or 2 (C5-C2o)alkyl substituent(s) and

1 aryl group that is phenyl or naphthyl; (v) a (C-| -C5)alkylphosphonic acid, wherein the (C-| - C5)alkyl is unsubstituted or substituted with one -NH2 group; (vi) HF, HCI, or HBr; (vii) a

Lewis acid; or (viii) a combination of any two or more of (i) to (vii).

5. The additive masterbatch composition of any one of claims 1 to 4 further comprising at least one additive selected from: (C) a secondary diarylamine of formula (I): (R1 -Ar)2NH

(I), wherein each Ar is benzene-1 ,4-diyl or both Ar are bonded to each other and taken together with the NH of formula (I) constitute a carbazol-3,6-diyl; and each R1 is independently (C-| -C2o)hydrocarbyl; (D) one or two second antioxidants, each having a structure different than formula (I) and each other; (E) a processing aid; (F) a colorant; (G) a metal deactivator; (H) an (unsaturated carbon-carbon bond)-free hydrolyzable silane; (I) a corrosion inhibitor; (J) a combination of any two or more of additives (D) to (I); and (K) a product of a reaction of (B) and (C).

6. The additive masterbatch composition of claim 5 further comprising the (K) product of a reaction of (B) and (C), wherein: (i) the product of a reaction of (B) and (C) comprises a salt formed by an acid/base reaction of (B) and (C); (ii) the additive package further comprises unreacted (B) but not unreacted (C); (iii) the additive package further comprises unreacted (C) but not unreacted (B) ; or (iv) the additive package further comprises unreacted (B) and unreacted (C).
