Abstract: Expandable plastic particles are formed by the polymerization of monomers containing at least 55% of a monovinyl aromatic compound using an aqueous suspension polymerization process in which the reaction mixture is polymerized under 100 DEG  C. until a polymer bead stage of at least 50% conversion of monomer to polymer is reached, then adding 3 to 10 weight per cent of a volatile liquid blowing agent within a period of 2 to 30 minutes and within the interval during which 50 to 80% of monomer is converted to polymer and completing the polymerization reaction at a temperature of at least 95 DEG  C. and preferably in the range 95 DEG  to 145 DEG  C. Styrene is the monomer preferred but vinyl naphthalenes and a -methyl styrene may also be used; such monovinyl aromatic compounds represent from 55 to 100% of the monomer and combinations may also be used. Ethylenically unsaturated compounds e.g. methyl methacrylate, acrylonitrile, dimethyl itaconate or divinyl benzene and mixtures thereof may also form up to 45% of the polymerization mixture if these are copolymerizable with the monovinyl aromatic compound. Suspending agents include polyvinyl alcohol, tricalcium phosphate, calcium carbonate, carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl-pyrrolidone, aluminium oxide and magnesium silicate. The pH of the suspension may be adjusted to 3.3 with phosphoric acid and benzoyl peroxide and t-butyl peracetate or lauryl peroxide, di-t-butyl paracresol and t-butyl peroxy isobutyrate may be used as catalyst.  The suspension may also contain tris (2,3-dibromopropyl) phosphate or a brominated polybutadiene so as to yield a self-extinguishing polymer.  In an example a mixture of styrene and SBR rubber was polymerized as above in the presence of benzoyl peroxide and n-dodecyl mercaptan.

[Class 79 (i).] Comprises a motor vehicle having front and rear road wheels and endless tracks for alternative use with the rear road wheels, in which the tracks are driven by means frictionally driven from the driving road wheels or a member coupled thereto, the arrangement being such that the friction drive only becomes effective as the weight of the vehicle is transferred wholly or partially from the driving wheels to the tracks. In the construction shown in Fig. 2, the track frames 1 are carried by links 2, 3 pivoted to the vehicle frame A and adapted to be actuated by jacks 8 so as to raise or lower the tracks from the ground. In the position shown the driving road wheels C are clear of the ground and pulleys 9 carried by the track frames and geared at 10, 11 to the track sprockets 6 are pressed against the wheels C so as to be frictionally driven thereby. Alternatively, the pulleys 9 may engage the wheels C while the latter are still in contact with the ground, the drive and the load then being distributed between the tracks and the road wheels. In the construction shown in Fig. 8, the tracks are carried by frames 1 detachably pivoted at 16 to the main frame A and having forks or stirrups at their rear ends 15 engaging the rear road wheel axle. In this construction the rear road wheel springs are partially compressed by the load on the tracks, and form an elastic connection between the tracks and the main frame. The tracks are driven by means of pulleys 9 which engage the road wheels and the external surfaces of the tracks. When the tracks are not in use the pivots 16 are disconnected and the track frames 1 are moved away from the rear wheel axle and jacked up on the main frame. Pulleys 9 may be provided with serrations engaging corresponding teeth on the tracks, these serrations on the pulleys being rough enough to give a good friction drive from the rear wheels without being sharp enough to damage them. The driving connection shown in Fig. 8 may be used with the construction shown in Fig. 2.
