Polymeric compositions of styrene and amorphous polyolefins useful in
preparing hot melt adhesives
摘要:
The present invention relates to novel polymeric compositions of styrene and amorphous polyolefins which include amorphous polypropylene, amorphous propylene/alpha-olefin copolymers and blends thereof and to processes for their preparation. These polymeric compositions are useful in preparing hot melt adhesives.
