Abstract

Particulate polymers are made by polymerizing at 40 DEG to 200 DEG C at least one monomer having a CH2=C< group in an agitated organic liquid which is inert to the polymer charge and a nonsolvent for the resultant polymer, and which contains a polymerization initiator, a chain transfer agent and a granulating agent, which last is preferably a copolymer of 99 to 70% of at least one C1-C18 alkyl acrylate or methacrylate in which the size of the alkyl group(s) is sufficiently large to solubilize the copolymer in the liquid organic medium, and 1 to 30% of at least one nitrogen compound having the formulae: <FORM:0956454/C3/1> where each of the R11 symbols represents hydrogen or a lower alkyl group, <FORM:0956454/C3/2> wherein R0 is hydrogen or a C1-C12 alkyl group and n is an integer of 1 to 4, or CH2=C(R)AYNR1R2 wherein R is hydrogen or methyl, A is oxygen, sulphur, <FORM:0956454/C3/3> or <FORM:0956454/C3/4> , Y is a C2-C8 alkylene group, R1 and R2, when not directly joined together, are phenyl, benzyl, methylbenzyl, cyclohexyl or C1-C6 alkyl groups, and, when directly joined together represent a morpholino, piperidino or pyrrolidino residue. Polymerizable CH2=C< monomers specified are C1-C4 alky methacrylates, C1-C18 alkyl and cyclohexyl acrylates, styrene, vinyl toluene, vinyl acetate and mixtures thereof with vinyl chloride, acrylonitrile, acrylic and methacrylic acids and amides, itaconic acid, dimethylaminoethyl acrylate, ureidoethyl vinyl ether, divinyl benzene and ethylene glycol dimethacrylate, which may be copolymerized with each other. Organic liquid polymerization media specified include aliphatic, cycloaliphatic and aromatic hydrocarbons, chlorinated aliphatic and aromatic hydrocarbons, petroleum fractions, terpenes, butyl stearate, ethyl dodecyl ether, ethylene glycol dodecyl ether and methyl tert.-dodecyl sulphide. Polymerization initiators specified are benzoyl peroxide, tert.-butyl hydroperoxide, tert.-butyl peracetate, azodiisobutyronitrile and methyl azodiisobutyrate. As a chain transfer agent there is specified 2-mercaptoethanol, and as a granulating agent there is specified a copolymer of N-vinyl -2- pyrrolidone, butyl acrylate and a mixture of C12-C18 alkyl methacrylates. The example describes the polymerization of methyl methacrylate in a petroleum fraction containing benzoyl peroxide, mercaptoethanol and the granulating agent specified above.
