摘要：
The subject invention provides reactive hot melt adhesive compositions comprising polyurethane prepolymers which have an isocyanate index greater than one and which are prepared from a low hydroxyl number composition comprising high molecular weight polyester diols which have a relatively low melting point. These reactive hot melt adhesive compositions have a faster setting speed than conventional reactive hot melt adhesive compositions. The subject invention also provides a method for bonding articles together which uses such reactive hot melt adhesive compositions and articles which comprise the reactive hot melt adhesive compositions.
