Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
37 words
A coextruded product characterised in that it has at least one surface layer of AES graft copolymer composition, the said AES comprising a graft copolymer of. resin-forming material on EPDM rubber in which the diene is dicyclopentadiene.
Claim 2
Dependent Claim
37 words
A coextruded product characterised in that it has at least one surface layer of AES graft copolymer composition, the said AES comprising a graft copolymer of. resin-forming material on EPDM rubber in which the diene is dicyclopentadiene.
Claim 3
Dependent Claim
17 words
A product according to claim 1 characterised in that it has an underlying layer of theromoplastic resin.
Claim 4
Dependent Claim
15 words
A product according to claim 2 characterised in that the underlying layer is ABS composition.
Claim 5
Dependent Claim
24 words
A coextruded product according to any of claims 1 to 3 characterised in that the resin-forming material in the AES graft copolymer is styrene-acrylonitrile.
Claim 6
Dependent Claim
83 words
A coextruded product characterised in that it has on one or both sides a surface layer 3 to 150 mils thick comprising AES graft copolymer composition containing up to 10 parts by weight of pigment per 100 parts by weight of AES graft copolymer composition, the said AES comprising a graft copolymer of resin-forming material on EPDM rubber in which the diene is dicyclopentadiene, and an underlying layer of ABS thermoplastic resin, the total thickness of the product being 25 to 500 mils.
Claim 7
Dependent Claim
83 words
A coextruded product characterised in that it has on one or both sides a surface layer 3 to 150 mils thick comprising AES graft copolymer composition containing up to 10 parts by weight of pigment per 100 parts by weight of AES graft copolymer composition, the said AES comprising a graft copolymer of resin-forming material on EPDM rubber in which the diene is dicyclopentadiene, and an underlying layer of ABS thermoplastic resin, the total thickness of the product being 25 to 500 mils.
Claim 8
Dependent Claim
47 words
