Abstract:
1. A paper coated with a paper coating slip, wherein the coating slip comprises a polymer produced by the emulsion polymerization of monomers having unsaturated radicals in the presence of at least two different polymerization regulators A) and B), wherein A) is terpinolene and B) is t-dodecyl mercaptan, wherein the amount of B) present during the emulsion polymerization is more than 2.15 parts by weight per 100 parts by weight of the monomers and the amount of A) present during the emulsion polymerization is from 0.02 to 0.7 parts by weight per 100 parts by weight of monomers; wherein at least 60% by weight of the monomers are butadiene or a mixture of butadiene and styrene, and wherein the paper has no occurrence of blisters after immersion in silicone fluid at 180° C. for two minutes in comparison to a comparative paper slip which is the same except includes a polymer made with less than 2.15 parts by weight of t-dodecyl mercaptan.
