Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
9 words
The polymer formed by the process of claim 1.
Claim 2
Dependent Claim
47 words
A process according to claim 1 wherein said decant oil is the heavy residue product obtained from catalytic cracking a gas oil, a topped crude oil, or admixtures thereof after fractionating off the lighter materials including heavy cycle oil, light cycle oil, cracked gasolines, and cracked gases.
Claim 3
Dependent Claim
18 words
