A and A' are end groups which may independently be a hydroxy group, a carboxy radical, a C.sub.1 -C.sub.8 alkoxy or a C.sub.6 -050249762 C.sub.10 aryloxy group. The compositions of the invention are characterized by their improved processability.

摘要： A Chemical Blowing Agent (CBA) concentrate was developed comprising a modifying agent and a chemical blowing agent. The CBA is characterized in that its decomposition products contain a primary amine. The modifying agent is a blend of a maleic anhydride copolymer and a butadiene based rubber. It was surprisingly found that resin degradation which often accompanies foam moldings using a CBA of the present type and is expressed in terms of a reduction in the molecular weight of the resin, is much reduced upon the incorporation of the modifying agent and chemical blowing agent of the invention. The concentrate may optionally further comprise a polymeric resin component.
