Abstract
Official abstract text for this publication.
Provided is an acryl-based copolymer, and more particularly, an acryl-based copolymer including a main monomer-derived repeating unit and a polyfunctional monomer-derived moiety, wherein the main monomer-derived repeating unit includes a (meth)acrylic acid alkyl ester monomer-derived repeating unit, a (meth)acrylic acid alkoxy alkyl ester monomer-derived repeating unit, and a crosslinkable monomer-derived repeating unit, the polyfunctional monomer includes a vinyl group or an allyl group, and the polyfunctional monomer-derived moiety is included in an amount of 0.0005 to 1 part by weight based on 100 parts by weight of the total main monomer-derived repeating unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acryl-based copolymer, consisting of a main monomer-derived repeating unit and a polyfunctional monomer-derived moiety, wherein the main monomer-derived repeating unit consists of a (meth)acrylic acid alkyl ester monomer-derived repeating unit, a (meth)acrylic acid alkoxy alkyl ester monomer-derived repeating unit, and a crosslinkable monomer-derived repeating unit, wherein the (meth)acrylic acid alkyl ester monomer-derived repeating unit is included in an amount of 82% by weight, the (meth)acrylic acid alkoxy alkyl ester monomer-derived repeating unit is included in an amount of 15% by weight, and the crosslinkable monomer-derived repeating unit is included in an amount of 3% by weight based on 100 parts by weight of main monomer mixture, wherein the polyfunctional monomer of the polyfunctional monomer-derived moiety; includes a vinyl group or an allyl group, wherein the polyfunctional monomer-derived moiety is included in an amount of 0.001 to 0.05 part by weight based on 100 parts by weight of a total main monomer-derived repeating unit, wherein the (meth)acrylic acid alkoxy alkyl ester monomer-derived repeating unit is one or more selected from the group consisting of methoxymethyl (meth)acrylate, ethoxyethyl (meth)acrylate, 2-ethoxyethyl (meth)acrylate, 2-butoxyethyl (meth)acrylate, 2-methoxyethyl (meth)acrylate, 2-propoxyethyl (meth)acrylate, 3-methoxypropyl (meth)acrylate, and 4-methoxybutyl (meth)acrylate, wherein the (meth)acrylic acid alkyl ester monomer-derived repeating unit is one or more selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate, isobutyl (meth)acrylate, n-amyl (meth)acrylate, isoamyl (meth)acrylate, n-hexyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, and cyclohexyl (meth)acrylate, wherein the crosslinkable monomer of the crosslinkable monomer-derived repeating unit is one or more selected from the group consisting of vinyl chloroacetate, vinyl benzyl chloride, 2-chloro ethyl acrylate, and 2-chloroethyl vinyl ether, and wherein the polyfunctional monomer is divinylbenzene or allyl methacrylate. 2. The acryl-based copolymer of claim 1 , wherein a Mooney viscosity (ML1+4, 100° C.) of the acryl-based copolymer is 10 to 70. 3. A method of preparing the acryl-based copolymer of claim 1 , the method comprising: preparing a main monomer mixture consisting of a (meth) acrylic alkyl ester monomer in an amount of 82% by weight, a (meth) acrylic acid alkoxy alkyl ester monomer in an amount of 15% by weight, and a crosslinkable monomer in an amount of 3% by weight based on 100 parts by weight of main monomer mixture, and adding a polyfunctional monomer to the main monomer mixture and polymerizing the mixture, wherein the polyfunctional monomer is added in an amount of 0.001 to 0.05 part by weight based on 100 parts by weight of a total main monomer mixture, and wherein the (meth)acrylic acid alkoxy alkyl ester monomer is one or more selected from the group consisting of methoxymethyl (meth)acrylate, ethoxyethyl (meth)acrylate, 2-ethoxyethyl (meth)acrylate, 2-butoxyethyl (meth)acrylate, 2-methoxyethyl (meth)acrylate, 2-propoxyethyl (meth)acrylate, 3-methoxypropyl (meth)acrylate, and 4-methoxybutyl (meth)acrylate, wherein the (meth)acrylic acid alkyl ester monomer-derived repeating unit is one or more selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate, isobutyl (meth)acrylate, n-amyl (meth)acrylate, isoamyl (meth)acrylate, n-hexyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, and cyclohexyl (methacrylate, wherein the crosslinkable monomer of the crosslinkable monomer-derived repeating unit is one or more selected from the group consisting of vinyl chloroacetate, vinyl benzyl chloride, 2-chloroethyl acrylate, and 2-chloroethyl vinyl ether and wherein the polyfunctional monomer is divinylbenzene or allyl methacrylate. 4. An acryl-based copolymer composition, comprising the acryl-based copolymer of claim 1 and a filler.
