A novel, branched, saturated, primary fatty acid amide is disclosed. Application areas are as a slip and/or antiblocking agent or mold release agent. The branched, saturated, primary fatty acid has a formula R&#x2014;CO&#x2014;NHwhere R is a saturated, branched hydrocarbon chain having 11 to 23 carbon atoms, wherein at least 60% by weight of the R&#x2014;CO&#x2014;NHmolecules have monoalkyl branches and less than 25% by weight of the R&#x2014;CO&#x2014;NHmolecules have polyalkyl branches.

Branched acids

Slip and antiblocking agent

Use of a composition consisting essentially of a mixture of aliphatic esters as a slip agent in a polyester polymer, said composition comprising at least two esters selected from the group comprising: Myristyl myristate, Myristyl palmitate, palmityl myristate, palmityl palmitate, palmityl stearate, stearyl myristate, stearyl palmitate, stearyl stearate, stearyl arachidate and stearyl behenate.

Compounds

Use of a compound of general formula (1) as a slip agent in a PET polymer, wherein: R and Rrepresent hydrocarbon moieties, each hydrocarbon moiety comprising 6 to 24 carbon atoms and wherein R and/or Rmay be linear, branched chain, saturated or contain one or more double a bonds; X represents one of the moieties (a), wherein A represents a hydrocarbon moiety comprising 2 to 36 carbon atoms and may be linear, branched chain, saturated or contain one or more double bonds.
