Abstract: Expandable styrene polymers which contain a C3-C6-hydrocarbon as a blowing agent, an organic bromine compound as a flameproofing agent and small amounts of ammonium salt and of an organic amine give, on expansion, foams which have a particularly homogenous foam structure and a good heat insulation effect.

Abstract: Flame-resistant, expandable styrene polymers containing a styrene (co)polymer, from 0.4 to 6% by weight of hexabromocyclododecane having a mean particle size of from 1 to 50 mu m, the particles being provided with a firm coating which has a thickness of from 1/100 to 1/10 of the particle diameter and is insoluble in water and styrene, from 1 to 10% by weight of a C3- to C6-hydrocarbon as blowing agent, and, if desired, customary additives, are distinguished by a reduced internal water content and can be processed to form foams which have an improved foam structure and high UV stability.

Abstract: Bead-form expandable styrene polymers are obtained by suspension polymerization of styrene with addition of from 1 to 10% by weight of C3- to C6-hydrocarbons as blowing agents and, if desired, customary additives, where (a) the polymerization is initiated by rapidly heating the polymerization batch to form 80 DEG to 90 DEG C. within a maximum of 2 hours, (b) subsequently allowing the reaction temperature to increase to from 120 DEG C. to 130 DEG C. by from 8 DEG to 17 DEG C. per hour, and (c) the conversion is formed 30 to 60% when 100 DEG C. is reached, and (d) the conversion is 80% or more when the maximum temperature is reached, and (e) the batch is subsequently kept at from 100 DEG to 130 DEG C. until the residual monomer content in the polymer has dropped to less than 0.1%.

Abstract: Bead-form expandable styrene polymers containing a styrene polymer having a mean molecular weight (weight average) of less than 130x103 and a steep high-molecular-weight flank of the molecular-weight distribution curve, and 0.15 to 1.5 mol of a C3- to C6-hydrocarbon as blowing agent, and, if desired, customary additives in effective amounts, are distinguished by a particularly high expansion capacity.
