A polycarbonate resin composition comprising (A) 20 to 94.6% by weight of a polycarbonate resin, (B) 50 to 5% by weight of a saturated polyester resin, (C) 15 to 0.2% by weight of a polyolefin resin, and (D) 15 to 0.2% by weight of an acrylate rubber-containing polyvinyl resin or an acrylate/methacrylate resin.
Claim 2
Dependent Claim
53 words
A polycarbonate resin composition comprising (A) 20 to 94.6% by weight of a polycarbonate resin, (B) 50 to 5% by weight of a saturated polyester resin, (C) 15 to 0.2% by weight of a polyolefin resin, and (D) 15 to 0.2% by weight of an acrylate rubber-containing polyvinyl resin or an acrylate/methacrylate resin.
Claim 3
Dependent Claim
15 words
The polycarbonate resin composition as claimed in Claim 1, wherein the polyolefin resin is polyethylene.
Claim 4
Dependent Claim
42 words
The polycarbonate resin composition as claimed in Claim 1, wherein the component (D) is an acrylate rubber-containing polyvinyl resin prepared by polymerizing at least one vinyl monomer in the presence of a rubber-like polymer composed mainly of alkyl acrylate and/or alkyl methacrylate.
Claim 5
Dependent Claim
28 words
The polycarbonate resin composition as claimed in Claim 3, wherein the alkylacrylate or alkyl methacrylate is one having an alkyl group of from 2 to 10 carbon atoms.
Claim 6
Dependent Claim
58 words
The polycarbonate resin composition as claimed in Claim 3, wherein the rubber-like polymer composed mainly of alkyl acrylate and/or alkyl methacrylate is a polymer prepared by reacting not less than 70% by weight of alkyl acrylate and/or alkyl methacrylate and not more than 30% by weight of other vinyl monomer copolymerizable with said alkyl acrylate and alkyl methacrylate.
Claim 7
Dependent Claim
55 words
The polycarbonate resin composition as claimed in Claim 3, wherein the rubber-like polymer composed mainly of alkyl acrylate and/or alkyl methacrylate is a polymer prepared by adding polyfunctional monomer selected from the group consisting of divinyl benzene, ethylene dimethacrylate, triallyl cyanurate and triallyl isocyanurate to the alkyl acrylate and/or alkyl methacrylate and other vinyl monomers.
Claim 8
Dependent Claim
60 words
The polycarbonate resin composition as claimed in Claim 3, wherein the component (D) is acrylate/methacrylate resin prepared by using acrylate which is an ester of saturated, straight aliphatic hydrocarbon having from 1 to 10 carbon atoms and acrylic acid, and methacrylate which is an ester of saturated, straight aliphatic hydrocarbon having from 1 to 10 carbon atoms and methacrylic acid.
Claim 9
Dependent Claim
47 words
The polycarbonate resin composition as claimed in Claim 7, wherein the acrylate is one selected from the group consisting of methylacrylate, ethylacrylate, isobutyl acrylate and n-butyl acrylate, and the methacrylate is one selected from the group consisting of methyl methacrylate, ethyl methacrylate, isobutyl methacrylate and n-butyl methacrylate.
