摘要:
The invention relates to readily processible polyamide molding compounds which have very good mechanical and electrical properties as well as high surface quality and are based on polyamide, magnesium hydroxide and polyhydroxy compounds of the Novolak type.
摘要:
The invention relates to a process for the production of caprolactam by thermal depolymerization of polyamide in the presence of small quantities of potassium carbonate at 250.degree. to 320.degree. C. and to a process for purifying the resulting caprolactam.
摘要:
The new polyphosphonates, which are highly branched through polyfunctional phosphorus compounds, are suitable for use as moldings, fibers or films and as flameproofing agents and stabilizers in plastics. The new highly branched polyphosphonates show high resistance to thermal ageing and ensure good processability coupled with high migration resistance at elevated in-use temperatures.
摘要:
The invention concerns a process for the manufcture of polyarylene sulphides from alkali sulphide and aromatic dihalogen compounds, whereby the alkali sulphide is produced in situ.
摘要:
The sensitivity of silver halide emulsions is increased if the silver halide is precipitated in the presence of a peptization agent which consists partially or wholly of a copolymer comprising 0.1 to 20 mol% of recurring structural units of the formula ##STR1## in which X is hydrogen or alkyl having 1 to 4 carbon atoms and Y is a 8-hydroxyquinoline group attached through its 5- or 7-position.
摘要:
The invention relates to polyamide molding compounds with increased viscosity, high thermal stability and favorable mechanical properties, to a process for their production and to their use.
摘要:
The present invention relates to a process for producing polymer blends from polycarbonate and mass-polymerized ABS by the condensation of oligocarbonate in the presence of mass-polymerized ABS.
