References Applied United States Patent 2,912,418 Nov. 10, 1959 Cl. 260-86.1 Johnson et al Chemical Abstract 54(1960) page 14158(b) The above cited patent discloses and claims a process for polymerizing a monomer such as styrene in the presence of an oil-soluble, free- radical-generating initiator such as benyoyl peroxide which comprises adding to the styrene a non-conjugated diolefinic compound such as allyl methacrylate. Example II in column 4 of the Patent specifically discloses such a process of polymerizing styrene with allyl methacrylate in the presence of benyoyl peroxide. The cited Chemical Abstract reference dis- closes a copolymer of styrene with allylstyrene. Applicant's claims 1 to 4 are rejected as being unpatentable in view of the cited references. Claim 1 is rejected as being too broad and indefinite in view of the dis- closure. According to the disclosure on page 2 lines 28 to 30, 0.05 to 0.35 per cent by weight, based on styrene, of the non-conjugated diolefinic comonomer is used. The claim must be restricted thereto.
