Abstract
Abstract This invention is directed to a composition for use as a material for the outer layer of a golf ball, which composition is produced by the reaction of an ionomer resin with a monoepoxy compound. The golf ball having the outer layer of such composition can be driven for a long distance with a soft shot feeling.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
In a golf ball comprising a core and an outer cover, the improvement wherein the outer cover is made from a composition which comprises the reaction product of (1) an ionomer resin comprising a copolymer of ethylene or an α-olefin and at least one unsaturated monocarboxylic acid having from 3 to 8 carbon atoms, said copolymer including thermo-modifiable metal cross-linkages therein, and (2) ethylene oxide or a monoepoxy compound having the formula: ##STR3## wherein R is alkyl, haloalkyl, alkenyl, cycloalkyl or phenyl.
Claim 2
Dependent Claim
82 words
In a golf ball comprising a core and an outer cover, the improvement wherein the outer cover is made from a composition which comprises the reaction product of (1) an ionomer resin comprising a copolymer of ethylene or an α-olefin and at least one unsaturated monocarboxylic acid having from 3 to 8 carbon atoms, said copolymer including thermo-modifiable metal cross-linkages therein, and (2) ethylene oxide or a monoepoxy compound having the formula: ##STR3## wherein R is alkyl, haloalkyl, alkenyl, cycloalkyl or phenyl.
Claim 3
Dependent Claim
38 words
A composition as claimed in claim 1, wherein said monoepoxy compound is selected from the group consisting of ethylene oxide, epichlorohydrin, allyl glycidyl ether, butyl glycidyl ether, cyclohexyl glycidyl ether, orthophenyl phenol glycidyl ether and phenyl glycidyl ether.
Claim 4
Dependent Claim
44 words
A composition as claimed in claim 1, wherein the reaction of the copolymer with ethylene oxide or the monoepoxy compound is performed in such a manner that the copolymer absorbs the ethylene oxide or monoepoxy compound after being heated to 90° to 95° C.
Claim 5
Dependent Claim
40 words
A composition as claimed in claim 1, wherein the reaction of the copolymer with ethylene oxide or the monoepoxy compound is performed in such a manner that the copolymer swells in a solution of the ethylene oxide or monoepoxy compound.
Claim 6
Dependent Claim
11 words
A composition as claimed in claim 1, further comprising a filler.
Claim 7
Dependent Claim
16 words
A composition as claimed in claim 5, wherein said filler comprises zinc oxide or magnesium oxide.
Claim 8
Dependent Claim
69 words
An outer layer for a golf ball having a composition comprising the reaction product of (1) an ionomer resin comprising a copolymer of ethylene or an α-olefin and at least one unsaturated monocarboxylic acid having from 3 to 8 carbon atoms, said copolymer including thermo-modifiable metal cross-linkages therein, and (2) ethylene oxide or a monoepoxy compound having the formula: ##STR4## wherein R is alkyl, haloalkyl, alkenyl, cycloalkyl or phenyl.
Claim 9
Dependent Claim
69 words
An outer layer for a golf ball having a composition comprising the reaction product of (1) an ionomer resin comprising a copolymer of ethylene or an α-olefin and at least one unsaturated monocarboxylic acid having from 3 to 8 carbon atoms, said copolymer including thermo-modifiable metal cross-linkages therein, and (2) ethylene oxide or a monoepoxy compound having the formula: ##STR4## wherein R is alkyl, haloalkyl, alkenyl, cycloalkyl or phenyl.
Claim 10
Dependent Claim
38 words
A composition as claimed in claim 7, wherein said monoepoxy compound is selected from the group consisting of ethylene oxide, epichlorohydrin, allyl glycidyl ether, butyl glycidyl ether, cyclohexyl glycidyl ether and phenyl glycidyl ether, orthophenyl phenol glycidyl ether.
Claim 11
Dependent Claim
11 words
A composition as claimed in claim 7, further comprising a filler.
Claim 12
Dependent Claim
16 words
A composition as claimed in claim 9, wherein said filler comprises zinc oxide or magnesium oxide.
