Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
A water emulsified composition containing 100 phr of a styrene/elastomer block copolymer in which an elastomer midblock comprises 60 to 90% of the copolymer and is isoprene or ethylene-butylene, about 20 to 80 phr of a poly(alpha-methylstyrene) having a softening point between about 200° and 300° F. and about 40 to 900 phr of a butylene polymer comprising 85-98% of mono-olefins.
Claim 2
Dependent Claim
61 words
A water emulsified composition containing 100 phr of a styrene/elastomer block copolymer in which an elastomer midblock comprises 60 to 90% of the copolymer and is isoprene or ethylene-butylene, about 20 to 80 phr of a poly(alpha-methylstyrene) having a softening point between about 200° and 300° F. and about 40 to 900 phr of a butylene polymer comprising 85-98% of mono-olefins.
