Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A COMPOUND OF THE FORMULA (R)MAR(O-E)N WHEREIN R IS A HYDROCARBON RADICAL CONTAINING AN OLEFINIC LINKAGE, M AND N ARE EACH INTEGERS OF 1 TO 3, AR IS AN AROMATIC NUCLEUS HAVING A VALENCE OF M+N, O IS AN ETHER OXYGEN ATOM, AND E IS A HYDROCARBON RADICAL CONTAINING AN EPOXIDE GROUP THEREIN WITH THE EPOXY OXYGEN ATOM LINKED TO OTHER THAN THE CARBON ATOM TO WHICH SAID ETHER OXYGEN ATOM IS DIRECTLY ATTACHED, SAID EPOXIDE GROUP BEING A THREE-MEMBERED RING.
Claim 2
Dependent Claim
81 words
A COMPOUND OF THE FORMULA (R)MAR(O-E)N WHEREIN R IS A HYDROCARBON RADICAL CONTAINING AN OLEFINIC LINKAGE, M AND N ARE EACH INTEGERS OF 1 TO 3, AR IS AN AROMATIC NUCLEUS HAVING A VALENCE OF M+N, O IS AN ETHER OXYGEN ATOM, AND E IS A HYDROCARBON RADICAL CONTAINING AN EPOXIDE GROUP THEREIN WITH THE EPOXY OXYGEN ATOM LINKED TO OTHER THAN THE CARBON ATOM TO WHICH SAID ETHER OXYGEN ATOM IS DIRECTLY ATTACHED, SAID EPOXIDE GROUP BEING A THREE-MEMBERED RING.
Claim 3
Dependent Claim
116 words
AN ADDITION COPOLYMER OF 1% TO 99% BY WEIGHT OF A COMPOUND OF THE FORMULA (R)MAR(O-E)N AND ANOTHER POLYMERIZABLE VINYLIDENE COMPOUND, WHEREIN SAID FORMULA R IS A HYDROCARBON RADICAL CONTAINING AN OLEFINIC LINKAGE, M AND N EACH INTEGERS OF 1 TO 3, AR IS AN AROMATIC NUCLEUS HAVING A VALENCE OF M + N, O IS AN ETHER OXYGEN ATOM, AND E IS AN HYDROCARBON RADICAL CONTAINING AN EPOXIDE GROUP THEREIN WITH THE EPOXY OXYGEN ATOM LINKED TO OTHER THAN THE CARBON ATOM TO WHICH SAID ETHER OXYGEN ATOM IS DIRECTLY ATTACHED, SAID EPOXIDE GROUP BEING A THREE-MEMBERED RING AND SAID COPOLYMER CONTAINING UNCHANGED EPOXY GROUPS AND HAVING ONLY CARBON ATOMS IN THE POLYMER CHAIN THEREOF.
Claim 4
Dependent Claim
116 words
AN ADDITION COPOLYMER OF 1% TO 99% BY WEIGHT OF A COMPOUND OF THE FORMULA (R)MAR(O-E)N AND ANOTHER POLYMERIZABLE VINYLIDENE COMPOUND, WHEREIN SAID FORMULA R IS A HYDROCARBON RADICAL CONTAINING AN OLEFINIC LINKAGE, M AND N EACH INTEGERS OF 1 TO 3, AR IS AN AROMATIC NUCLEUS HAVING A VALENCE OF M + N, O IS AN ETHER OXYGEN ATOM, AND E IS AN HYDROCARBON RADICAL CONTAINING AN EPOXIDE GROUP THEREIN WITH THE EPOXY OXYGEN ATOM LINKED TO OTHER THAN THE CARBON ATOM TO WHICH SAID ETHER OXYGEN ATOM IS DIRECTLY ATTACHED, SAID EPOXIDE GROUP BEING A THREE-MEMBERED RING AND SAID COPOLYMER CONTAINING UNCHANGED EPOXY GROUPS AND HAVING ONLY CARBON ATOMS IN THE POLYMER CHAIN THEREOF.
