摘要:
The invention relates to elastic-thermoplastic and thermoplastic pulverulent moulding materials and to mixtures thereof, which can be processed as thermoplastics, with elastic moulding materials, which are prepared from the corresponding aqueous latices under salt-free conditions using a purely organic precipitating agent system.
摘要:
Polymer alloys having a mat surface constituting a mixture of grafted rubbers, the graft superstrate containing an acidic monomer in one part of the mixture and a basic monomer in the other part.
摘要:
The invention relates to thermoplastic molding compounds of 70 to 99.5% by weight thermoplastic polyamides and 30 to 0.5% by weight hydrogenated nitrile rubber and 0 to 29.5% by weight thermoplastic resin components and, optionally, standard additives in typical quantities. These thermoplastic molding compounds show high strength values, very good moldability and, above all, high weathering resistance.

The invention relates to new block copolymers consisting of recurring polysiloxane blocks and recurring conjugated diene homo-or copolymer blocks with particularly good rubber properties, in particular at low temperatures.
摘要:
A graft product of from 40 to 99.8 parts by weight of styrene, .alpha.-methyl styrene, p-methyl styrene, vinyl toluene, methyl methacrylate or mixtures thereof, from 20 to 0.1 part by weight of a vinyl-group-containing, preferably heterocyclic nitrogen base, from 20 to 0.1 part by weight of a mono- or di-acid containing a polymerizable double bond and from 0 to 49 parts by weight of acrylonitrile on a particulate rubber having an average particle diameter (d.sub.50) of from 0.05 to 20.0 .mu.m and a glass temperature of .ltoreq.10.degree. C., the total rubber content amounting to between 5 and 80% by weight.
摘要:
The thermoplastic moulding compounds according to the invention obtained from aromatic polyester carbonates and special graft polymers have a very high weld-line strength as well as a high notched impact strength at room temperature and especially at low temperatures and may be used for the production of moulded articles.
摘要:
Polycarbonate molding compositions resistant to light aging and exhibiting an improved notched impact strength are disclosed. The compositions which are based on an aromatic polycarbonate, aromatic polyester carbonate or a polyester, contain a redox-catalyzed graft polymer of resin-forming monomers on a rubber, a phosphorus compound and a fluorinated polyolefin.
