Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A method of storing a polymer having a silyl group for long periods of time without any substantial amount of increase in the viscosity of said polymer, consisting of mixing 100 parts by weight of said polymer, said polymer having at least one silyl group per molecule having the formula: ##STR2## wherein R.sub., R 2 , R 3 is a hydrogen atom or a monovalent hydrocarbon group selected form alkyl, aryl, or aralkyl group having 1 to 10 carbon atoms, X is a group selected from alkoxy, acryloxy, aminooxy, phenoxy, thioalkyoxy, or amino group, and a is an integer 0, 1 or 2, with about 10 to 50 parts by weight of a stabilizer consisting of one or more aliphatic or aromatic monohydric alcohol having 1 to 10 carbon atoms; and wherein said polymer is a member selected from the group consisting of polyester, polether, ether-ester block copolymer, vinyl polymer, diallyl phthalate monomer or polymer, and a mixture thereof; and wherein said polymer has a molecular weight of between 1,200 and 9,000.
Claim 2
Independent Claim
172 words
A method of storing a polymer having a silyl group for long periods of time without any substantial amount of increase in the viscosity of said polymer, consisting of mixing 100 parts by weight of said polymer, said polymer having at least one silyl group per molecule having the formula: ##STR2## wherein R.sub., R 2 , R 3 is a hydrogen atom or a monovalent hydrocarbon group selected form alkyl, aryl, or aralkyl group having 1 to 10 carbon atoms, X is a group selected from alkoxy, acryloxy, aminooxy, phenoxy, thioalkyoxy, or amino group, and a is an integer 0, 1 or 2, with about 10 to 50 parts by weight of a stabilizer consisting of one or more aliphatic or aromatic monohydric alcohol having 1 to 10 carbon atoms; and wherein said polymer is a member selected from the group consisting of polyester, polether, ether-ester block copolymer, vinyl polymer, diallyl phthalate monomer or polymer, and a mixture thereof; and wherein said polymer has a molecular weight of between 1,200 and 9,000.
Claim 3
Dependent Claim
162 words
A composition consisting of a stabilizer consisting of an alcohol and a polymer having at least one silyl group per molecule of the general formula: ##STR3## wherein R 1 , R 2 , R 3 is a hydrogen atom or a monovalent hydrocarbon group selected from alkyl, aryl or aralkyl group having 1 to 10 carbon atoms, X is a group selected from alkoxy, acyloxy, aminoxy, phenoxy, thioalkoxy or amino group, and a is an integer of 0, 1 or 2; and wherein said alcohol is one or more aliphatic or aromatic monohydric alcohol having 1 to 10 carbon atoms in an amount of from about 10 to 50 parts by weight to 100 parts by weight of said polymer; and wherein said polymer is a member selected from the group consisting of polyester, polyether, ether-ester block copolymer, vinyl polymer, diallyl phthalate monomer or polymer and a mixture thereof; and wherein said polymer has a molecular weight of between 1,200 and 9,000.
Claim 4
Dependent Claim
162 words
A composition consisting of a stabilizer consisting of an alcohol and a polymer having at least one silyl group per molecule of the general formula: ##STR3## wherein R 1 , R 2 , R 3 is a hydrogen atom or a monovalent hydrocarbon group selected from alkyl, aryl or aralkyl group having 1 to 10 carbon atoms, X is a group selected from alkoxy, acyloxy, aminoxy, phenoxy, thioalkoxy or amino group, and a is an integer of 0, 1 or 2; and wherein said alcohol is one or more aliphatic or aromatic monohydric alcohol having 1 to 10 carbon atoms in an amount of from about 10 to 50 parts by weight to 100 parts by weight of said polymer; and wherein said polymer is a member selected from the group consisting of polyester, polyether, ether-ester block copolymer, vinyl polymer, diallyl phthalate monomer or polymer and a mixture thereof; and wherein said polymer has a molecular weight of between 1,200 and 9,000.
