Abstract:
The invention relates to expandable or expanded thermoplastic polymer particles provided with a coating containing hydrophobin, especially proteins of general structural formula (I): X n -C 1 -X 1-50 -C 2 -X 0-5 -C 3 -X 1-100 -C 4 -X 1-100 -C 5 -X 1-50 -C 6 -X 0-5 -C 7 -X 1-50 -C 8 -X m wherein X represents each of the 20 naturally occurring amino acids, n and m represent numbers between 0 and 500, and C represents cysteine. The invention also relates to the use of said particles as an antistatic agent.
Abstract:
A process for preparing expandable styrene polymers with narrow bead size distribution, which can be processed to foams with homogeneous cell structure and low thermal conductivity, by polymerizing the monomers in aqueous suspension in the presence of a volatile blowing agent and from 0.1 to 30 ppm, based on the organic phase, of a hydroxyalkylamine.
