Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
34 words
A process as in claim 1 wherein the abrasives are first mixed with said liquid binder component, thereafter mixed with an adsorption agent for said liquid binder component, and then mixed with said polyester.
Claim 2
Dependent Claim
35 words
A process as in claim 2 wherein the abrasives are first mixed with said liquid binder component and thereafter mixed with a mixture of an adsorption agent for said liquid binder component and said polyester.
Claim 3
Dependent Claim
33 words
A process as in claim 3 wherein the abrasives are first mixed with an adsorbate consisting of said liquid binder component adsorbed on an adsorption agent therefor, and thereafter mixed with said polyester.
Claim 4
Dependent Claim
102 words
A process for the manufacture of molded articles which contain abrasives in an organic binder, said binder being a thermosetting material formed by the copolymerization of an unsaturated polyester with one or more polymerizable ethylenically unsatuRated monomers, which process comprises: treating the abrasives with a surface-active bonding agent, thereafter mixing the abrasives with a liquid binder component comprising essentially one or more liquid polymerizable ethylenically unsaturated monomers, then mixing, as a further binder component, a dry unsaturated polyester into the above mixture, thereafter compacting the resultant mixture into a free-standing stable body, and hardening such body by copolymerization of said binder components.
Claim 5
Dependent Claim
18 words
A process as in claim 5 wherein the surface-active bonding agent is added to the liquid binder component.
Claim 6
Dependent Claim
17 words
A process as in claim 5 wherein silanes or chromium-chloride-methacrylate-complexes are employed as the surface-active bonding agents.
Claim 7
Dependent Claim
15 words
A process as in claim 6 wherein silanes are employed as the surface-active bonding agents.
Claim 8
Dependent Claim
16 words
A process as in claim 1 wherein the organic binder is copolymerized with a cross-linking agent.
Claim 9
Dependent Claim
16 words
A process as in claim 5 wherein the organic binder is copolymerized with a cross-linking agent.
Claim 10
Dependent Claim
112 words
A process for the manufacture of molded articles which contain abrasives in an organic binder, said binder being a thermosetting material formed by the copolymerization of an unsaturated polyester with one or more polymerizable ethylenically unsaturated monomers, which process comprises: treating the abrasives with a surface-active bonding agent, thereafter mixing the abrasives with a liquid binder component comprising essentially one or more liquid polymerizable ethylenically unsaturated monomers, and with an adsorption agent for said liquid binder component, then mixing, as a further binder component, a dry unsaturated polyester into the above mixture, thereafter compacting the resultant mixture into a free-standing stable body, and hardening such body by copolymerization of said binder components.
Claim 11
Dependent Claim
19 words
A process as in claim 11 wherein the surface active bonding agent is added to the liquid binder component.
Claim 12
Dependent Claim
33 words
Abrasive articles comprising abrasive grains, an organic binder consisting essentially of the copolymerization product of an unsaturated polyester with one or more polymerizable liquid ethylenically unsaturated monomers, and an adsorbent for said monomers.
Claim 13
Dependent Claim
32 words
Abrasive articles comprising abrasive grains, an organic binder consisting essentially of the copolymerization product of an unsaturated polyester with one or more polymerizable liquid ethylenically unsaturated monomers, and a surface-active bonding agent.
Claim 14
Dependent Claim
37 words
Abrasive articles comprising abrasive grains, an organic binder consisting essentially of the copolymerization product of an unsaturated polyester with one or more polymerizable liquid ethylenically unsaturated monomers, a surface-active bonding agent, and an adsorbent for said monomers.
Claim 15
Dependent Claim
36 words
Abrasive articles comprising abrasive grains, an organic binder consisting essentially of the copolymerization product of an unsaturated polyester with one or more polymerizable, liquid ethylenically unsaturated monomers, a cross-linking agent, and an adsorbent for said monomers.
Claim 16
Dependent Claim
40 words
Abrasive articles comprising abrasive grains, an organic binder consisting essentially of the copolymerization product of an unsaturated polyester with one or more polymerizable liquid ethylenically unsaturated monomers, a cross-linking agent, a surface-active bonding agent, and an adsorbent for said monomers.
