The invention relates to a process for production of expanded pellets from a polymer melt comprising a blowing agent, said process comprising the steps of:

Method for producing expanded granules

Expandable-polymer-particle material comprising at least one thermoplastic polyurethane (TPU) with Vicat softening point (in accordance with ISO 306/ASO) below 80&#xb0; C. and from 5 to 95% by weight of at least one polymer obtainable via free-radical polymerization, based on the entirety of TPU and of the polymer obtainable via free-radical polymerization, where the polymer obtainable via free-radical polymerization has been bonded to the TPU in a manner that gives a comb polymer, graft polymer, or copolymer, is suitable for the production of moldings, in particular for use as insulation material.

Polyurethane-based expandable polymer particles

A composition comprising at least one expandable styrene polymer component and at least one cyclohexanecarboxylic ester and also optionally further components can be processed to mechanically robust foam materials.

Process for producing expandable styrene polymer compositions

The invention provides a process for preparing expandable styrene polymers which comprises the steps of:

Preparing expandable styrene polymers

Expandable styrene polymers (EPS) comprising, in each case based on the styrene polymer,

Flameproof expandable styrene polymers, and method for the production thereof

Expandable pelletized styrene polymer materials with at least bi- or multimodal molecular weight distribution, to a process for their preparation, and to use for producing moldable-foam moldings.

Expandable polystyrene granulates with a bi- or multi-modal molecular-weight distribution

A process for the preparation of expandable styrene polymers having a molecular weight Mof greater than 170,000 g/mol, which comprises conveying a blowing agent-containing styrene polymer melt having a temperature of at least 120&#xb0; C. through a die plate with holes whose diameter at the die exit is at most 1.5 mm, and subsequently granulating the extrudate, and expandable styrene polymers (EPS) having a molecular weight Mof more than 170,000 g/mol with 0.05 to 1.5% by weight of internal water.

Method for producing expandable polystyrene

An anti-lumping agent for use with expandable polystyrene beads is disclosed. The expandable polystyrene beads comprise a styrene or styrene derivative polymer in combination with a blowing agent. Typical blowing agents are C -C hydrocarbons, with pentane being especially preferred. The anti-lumping agents include block copolymers formed from blocks of ethylene oxide and propylene oxide. Preferably, the copolymers have a number average molecular weight of from about 4,000 to 15,000, and a hydrophilic-lipophilic balance number of from about 16 to 29. The anti-lumping agents significantly reduce the lumping potential of the expandable polystyrene beads, especially when they are expanded to low densities of from about 1.5 to 0.75 lbs. per cubic foot, and more preferably to densities of from about 1.2 to 0.85.

Anti-lumping compounds for use with expandable polystyrene beads

Hirudin/polyalkylene glycol conjugates and hirudin muteins

The invention relates to a process for the preparation of bead shaped, expandable polystyrene by the polymerization of styrene in an aqueous suspension in the presence of dimeric .alpha.-methylstyrene as a regulator and a C.sub.3 to C.sub.6 hydrocarbon as a blowing agent, whereby one first reports the content of saturated hydrocarbons, having a boiling point between 70.degree. and 170.degree. C., in the styrene and dimeric .alpha.-methylstyrene, and then enough saturated hydrocarbons, having a boiling point from 70.degree. to 170.degree. C., are added before, during or after the polymerization so that their total content in the suspension is from 0.1 to 0.8 weight percent, based on the styrene.
