Highly filled thermoplastic carpet precoat compositions

A precoat composition comprising a blend of

• (A) 18-28 wt. % total ethylene/vinyl acetate copolymer comprising at least one ethylene/vinyl acetate copolymer wherein at least 30 wt. % of the total ethylene/vinyl acetate copolymer is an ethylene/vinyl acetate copolymer with a melt index of greater than 300, prepared using a substantially non-incorporating chain transfer agent, selected from the group consisting of acetone and propane, wherein the average vinyl acetate content of the total ethylene/vinyl acetate copolymer is from 20-32 wt. %, and wherein the vinyl acetate content of any one ethylene/vinyl acetate copolymer is from 10 to 40 wt. %,
• (B) 4-12 wt. % processing oil,
• (C) 60-80 wt. % of a filler,
• (D) 0-1 wt. % of an organic acid selected from stearic, oleic, palmitic and dimers and trimers thereof, wherein the melt index of the blend is from 60 to 300;
• the total of (A), (B), (C), (D) equalling 100%.
