Claim 1
Independent Claim
33 words
A calcium resinate comprising the reaction product of calcium hydroxide and rosins with (a) 1-25% by weight of a reactive hydrocarbon resin, and (b) 3-30% by weight of a polyanhydride of α-olefin-maleic anhydride.
Claim 2
Dependent Claim
33 words
A calcium resinate comprising the reaction product of calcium hydroxide and rosins with (a) 1-25% by weight of a reactive hydrocarbon resin, and (b) 3-30% by weight of a polyanhydride of α-olefin-maleic anhydride.
Claim 3
Dependent Claim
23 words
The calcium resinate of claim 1 wherein the rosin is selected from the group consisting of tall oil, wood, gum and polymerized rosin.
