Abstract
A hot melt adhesive composition comprising PA1 (i) 10 to 90% by weight of a sulfonated polyester condensation polymer; PA1 (ii) 0 to 80% by weight of a compatible tackifier; PA1 (iii) 0 to 40% by weight of a compatible plasticizer; PA1 (iv) 5 to 40% by weight of a compatible wax diluent with a molecular weight below 500 g/mole containing at least one polar functional group, said group being present at a concentration greater than 3.times.10.sup.-3 equivalents per gram; PA1 (v) 0 to 60% by weight of a compatible crystalline thermoplastic polymer; and PA1 (vi) 0 to 3% by weight of a stabilizer, the total of (i)-(vi) to equal 100% by weight.
