Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
POLYETHER GLYCOLS OF AT LEAST ABOUT250 AND NO MORE THAN 16,000 MOLECULAR WEIGHT HAVING AT LEAST ONE UNSATURATED BOND FOR EACH 8,000 UNITS OF MOLECULAR WEIGHT COMPRISING THE COPOLYMERIC REACTION PRODUCT OF (1) A SATURATED HETEROCYCLIC COMPOUND HAVING A RING CONSISTING OF AT LEAST 2 CARBON ATOMS AND ONE OXYGEN ATOM, SAID RING BEING SELECTED FROM THE CALSS CONSISTING OF THOSE CONTAINING 3, 4, 5, AND 1 TOTAL ATOMS PER RING WITH (2) AN EPOXY ALIPHATIC MONOMER CONTAINING AT LEAST ONE ETHYLENIC DOBULE BOND AND HAVING A MOLECULAR WEIGHT LESS THAN ABOUT 240, WHICH IS HYDROXYL TERMINATED TO GIVE SUBSTANTIALLY AT LEAST 2 HYDROXYLS PER MOLECULE, THE COPOLYMERIC REACTION OCCURRING IN THE PRESENCE OF .5 TO ABOUT 10% BY WEIGHT OF THE COPOLYMERIZATION REACTANTS OF A LEWIS ACID CATALYST CAPABLE OF DECOMPOSING THE CARBON-OXYGEN BOND IN THE RING OF A MONOMER CONTAINING AT LEAST TWO CARBON ATOMS AND ONE OXYGEN IN SAID RING TO INITIATE POLYMERIZATION THEREOF,

Claim 3
Dependent Claim
146 words
A PROCESS FOR PRODUCING POLYHYDROXYL TERMINATED POLYETHERS HAVING A MOLECULAR WEIGHT OF AT LEAST 250 AND NO MORE THAN ABOUT 16,000 WITH AT LEAST ONEDOUBLE BOND FOR EACH 8,000 UNITS OF MOLECULAR WEIGHT COMPRISING COPOLYMERIZING IN THE PRESENCE OF .5 TO ABOUT 10% BY WEIGHT OF THE COPOLYMERIZATION REACTANTS OF A LWEIS ACID CATALYST CAPABLE OFDECOMPOSING THE CARBON-OXYGENBOND IN THE RING OF A MONOMER CONTAINING AT LEAST TWO CARBON ATOMS AND ONE OXYGEN IN SAID RING TO INITIATE POLYMERIZATION THEREOF, (1) A SATURATED HETEROCYCLIC COMPOUND HAVING A RING CONSISTING OF AT LEAST TWO CARBON ATOMS AND ONE OXYGEN ATOM, SAID RING BEING SELECTED FROM THE CLASS CONSISTING OF THOSE CONTAINING 3, 4, 5, AND 7 TOTAL ATOMS PER RING WITH 3(2) AN EPOXY ALIPHATIC MONOMER HAVING A MOLECULAR WEIGHT LESS THAN 240 AND THEN TREATING THE COPOLYMERIZATION PRODUCT WITH SUFFICIENT WATER TO DECOMPOSE THE CATALYST COMPLEX.
