[Class 2 (iii)] Lubricated moulding compositions are produced by dispersing one or more ethenoid monomers, i.e. containing the group CH 2  = C<, in water containing a dispersing agent, initiating polymerization and adding during " the peak period of the polymerization one or more saturated aliphatic acids containing from 12 to 18 carbon atoms inclusive. The preferred proportions of acid are up to 2 parts per 100 parts by weight of the monomer(s) and specified acids are stearic, palmitic, myristic and lauric. " The peak period of polymerization " during the process of dispersion polymerization is the time during which the temperature of the reaction mix rises abruptly to a maximum and drops just as rapidly to its initial level. Specified ethenoid monomers are methyl methacrylate, vinyl acetate and other esters, styrene and its derivatives, and other esters of acrylic and methacrylic acids. These monomers may be used alone or as mixtures. Plasticizers may be added to the polymerization reaction and the granular polymer may be compounded with auxiliary ingredients, i.e. colours. In examples the aqueous vehicle contains mono- and di-sodium phosphates and a partially neutralized polymethacrylic acid solution as granulating agent. Monomeric methyl methacrylate alone in (1), (5), (6) and (7) or with (2) styrene, (3) methyl acrylate, (4) vinyl acetate, is polymerized in dispersion with benzoyl peroxide (in examples (5) and (7) diamyl phthalate plasticizer is added) and at the peak period stearic acid is added (palmitic in (5) and myristic in (7)). The dried polymer of (4) is compounded on rolls with Cadmium Yellow No. 4.
