Polyamide blend composition having excellent gas barrier performance

A process for forming a polyamide composition comprising combining:

• (i) a first polyamide comprising a crystallizable polyamide homopolymer, a crystallizable polyamide copolymer, a crystallizable polyamide nanocomposite, or a blend thereof;
• and
• (ii) a semi-crystalline second polyamide comprising a polyamide copolymer comprising from about 40% to about 60% by weight of an m-xylylene diamine moiety, from about 5% to about 15% by weight of an isophthalic acid moiety, and from about 30% to about 50% by weight of an aliphatic dicarboxylic add precursor, and an optional clay.

A process for forming a polymeric composition comprising combining at least one polymer component with a polyamide composition component, the polyamide composition component comprising:

• (i) a first polyamide comprising a crystallizable polyamide homopolymer, a crystallizable polyamide copolymer, a crystallizable polyamide nanocomposite, or a blend thereof;
• and
• (ii) a semi-crystalline second polyamide comprising a polyamide copolymer comprising from about 40% to about 60% by weight of an m-xylylene diamine moiety, from about 5% to about 15% by weight of an isophthalic acid moiety, and from about 30% to about 50% by weight of an aliphatic dicarboxylic acid precursor, and an optional clay.
