  • Patent number: 9006318
    Abstract: The present invention relates to a polyamide composition comprising (amounts are based on the total composition) (A) polyamide, (B) melamine cyanurate and (C) talcum as mineral filler wherein the amount of talcum is higher than 25 wt %, and the weight ratio melamine cyanurate/talcum is higher than ? and to articles made wholly or partly of this polyamide composition. The polyamide is preferably polyamide 6. The composition is commonly used in the industry of for instance electrical and electronic parts and preferably in miniature circuit breakers.
    Type: Grant

  • Patent number: 6242540
    Abstract: Particles of a copolymer of a vinyl arene and a copolymerizable compound containing a polar moiety and a vinyl moiety containing water may be prepared by forming a mixture of monomers and small amounts of water and polymerizing under agitation to 20 to 70% conversion and then suspending the mass in water and finishing the polymerization. The resulting polymer beads contain finely dispersed water which is useful as an environmentally acceptable blowing agent.

  • Patent number: 6160027
    Abstract: It is desirable to reduce the amount of volatile organic blowing agent in expandable polystyrene. This may be accomplished by partially polymerizing a mass of styrene and incorporating therein water together with an emulsifier. The partially polymerized mass is then polymerized to a high conversion using conventional suspension techniques. The polymer beads containing water which acts as a blowing agent are recovered.
