Abstract:
The invention relates to highly branched or hyperbranched polycarbonates based on dialkyl- or diarylcarbonates or phosgene, diphosgene or triphosgene and aliphatic and aromatic diols or polyols. The invention also relates to a method for producing the same and to their use in the production of printing inks.
Abstract:
Multi-layered materials for producing packaging comprising at least 2 sheets and a layer printed with a printing ink, wherein the printing ink contains a hyper-branched polyester comprising functional groups. Printing ink containing a polyester comprising functional groups. Use of said printing ink in the production of multi-layered materials.
Abstract:
The invention relates to a continuous method for producing polyalkylene arylates A) containing highly branched or hyperbranched polymers B) and optionally lubricants C). According to said method, an aromatic dicarboxylic acid or esters thereof or ester forming derivatives are esterified or interesterified with a molar surplus of an aliphatic dihydroxy compound and the resultant interestification or esterification product is polycondensed. The method is characterised in that component B) and optionally component C) is/are added to the polymer melt when at least 80 % of the desired viscosity number has been reached and the melt is optionally recondensed, discharged, cooled and granulated and that component B is composed of at least one highly branched or hyperbranched polycarbonate B1) with an OH number of between 1 and 600 mg KOH/g polycarbonate (conforming to DIN 53240, part 2), or at least one highly branched or hyperbranched polyester B2) of the type AxBy, where x equals at least 1.1 and y equals at least 2.1, or mixtures thereof.
Abstract:
The present invention relates to silylated amino resins, to processes for preparation thereof, to the use thereof and to coating compositions comprising them.
Abstract:
Thermoplastic molding compounds comprising: A) 10 to 98 % by weight of at least one thermoplastic polyester, B) 0.01 to 50 % by weight of B1) at least one highly branched or hyperbranched polycarbonate having an OH number of 1 to 600 mg KOH/g of polycarbonate (according to DIN 53240, part 2), or B2) at least one highly branched or hyperbranched type AxBy polyester, wherein x is at least 1.1 and y at least 2.1 and the mixtures thereof, C) 1 to 40 % by weight of an impact-resistant modified polymer, D) 0 to 60 % by weight of other additives, whereby the sum of the weight percentages of components A) to D) adds up to 100 %.
Abstract:
The invention relates to a method for the production of highly functional, highly branched polyureas. One or several ureas are transformed by means of one or several amines having at least two primary and/or secondary amino groups. At least one amine comprises at least three primary and/or secondary amino groups.
Abstract:
The invention relates to curable compounds that comprise epoxy resins, amino hardeners and a phosphonate from formula (I). By adding of phosphonate from formula (I), hardened epoxy resins are obtained according to the invention, which hardened epoxy resins have both an improved fire retardancy and an increased glass transition temperature relative to the corresponding resins without said addition.
