Abstract
Thermoplastic polyolefin polymer composition, polymer chip, fiber, woven or nonwoven fabric, film, closures, laminates can comprise a polymer, a polymer and a nonvolatile polymer-compatible carboxylic acid. Thermoplastic polyolefin polymer composition can also comprise a polymer, a cyclodextrin-modified polymer and a nonvolatile polymer-compatible carboxylic acid. The carboxylic acid moiety of the polymer composition can react with basic materials in the polymer environment and reduce release of the basic material. The cyclodextrin can act to absorb or trap other contaminants or odors in the environment.

A thermoplastic polymer composition, comprising
- (i) a blend of:
- (1) a major proportion of a polyolefin resin and
- (2) about 1 wt % to 47 wt % of a modified polyolefin resin, and
- (ii) from about 0.1 wt % to about 5 wt % of a non-volatile and polymer compatible carboxylic acid based on the polymer composition.
A thermoplastic polymer masterbatch, comprising
- (i) a blend of a major proportion of a polyolefin resin;
- and
- (ii) from about 1 wt % to about 15 wt % a non-volatile and polymer compatible carboxylic acid based on the polymer composition.
