CLAIMS

What is claimed is:

1. A hot melt adhesive, comprising: a poly(lactide) homopolymer or copolymer with a molecular weight of about 1000 to about 40000 Daltons; anda plasticizer comprising an ester with about 50% to about 100% bio-based content; wherein the viscosity of the hot melt adhesive composition is about 500 to about 15,000 cPs...

DESCRIPTION

BACKGROUND

Hot melt adhesives (HMAs) are solids at room temperature, but when heated form a liquid adhesive layer that cools and bonds rapidly to a substrate. HMAs can be useful for high speed manufacturing and applications that require bonding versatility, large gap filling, and minimal shrinkage. HMAs do not require a...
