Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
84 words
A one-pack type curable resin composition
comprising: (A) an oxyalkylene base polymer having at least
one silicon atom-containing group whose silicon atom is
attached to a hydroxyl group or a hydrolyzable group, (B) a filler, (C) a plasticizer, (D) a curing catalyst ccmprising a tetravalent tin
compound, and (E) an organic carboxylic acid in an
amount of 0.01-10 parts by weight per 100 parts by weight of
the oxyalkylene base polymer (A), excluding a fatty acid
used to surface treat a calcium carbonate filler.
Claim 2
Dependent Claim
170 words
A one-pack type curable resin composition
according to Claim 1, wherein said silicon-containing group
is a group of the formula: wherein R 1 and R 2 are the same or different and each is an
alkyl group having 1 to 20 carbon atoms, an aryl group
having 6 to 20 carbon atoms, an aralkyl group having 7 to 20
carbon atoms or a triorganosiloxy group of the formula: (R') 3 SiO- in which R' is a monovalent hydrocarbon group having 1 to 20
carbon atoms provided that three R' groups may be the same
or different; X is a hydroxyl group or a hydrolyzable group
provided that when two or more X groups are present, they
may be the same or different; a is 0, 1, 2 or 3; b is 0, 1
or 2 provided b in different groups in the brackets may
be the same or different; m is an integer of 0 to 19 provided
that the sum of a and all b's is at least one.
Claim 3
Dependent Claim
31 words
A curable resin composition according to
Claim 2, wherein said silicon-containing group is a group of
the formula: wherein R 2 , X and a are the same as defined above.
Claim 4
Dependent Claim
25 words
A curable resin composition according to
Claim 2, wherein said silicon-containing group is a group of
the formula: -Si(CH 3 )(OCH 3 ) 2 .
Claim 5
Dependent Claim
18 words
A curable resin composition according to
Claim 1, wherein said oxyalkylene base polymer (A) is an
oxypropylene polymer.
Claim 6
Dependent Claim
15 words
A curable resin composition according to
Claim 1, wherein said filler (B) is calcium carbonate.
Claim 7
Dependent Claim
16 words
A curable resin composition according to
Claim 1, wherein said plasticizer (C) is an ester plasticizer.
Claim 8
Dependent Claim
15 words
A curable resin composition according to
Claim 7, wherein said ester plasticizer is di(2-ethylhexyl)
phthalate.
Claim 9
Dependent Claim
19 words
A curable resin composition according to
Claim 1, wherein said tetravalent tin compound is a dialkyl-tin
dicarboxylic acid salt.
Claim 10
Dependent Claim
25 words
A curable resin composition according to
Claim 1, wherein said organic carboxylic acid (E) is an
aliphatic monocarboxylic acid having 2 to 30 carbon atoms.
