Abstract:
Shaped articles having long term vapor emission comprising a thermosetting resin produced from an unsaturated polyester and a vinyl monomer copolymerizable therewith, containing an effective amount of 0,0-dimethyl-0-(2,2-dichlorovinyl)-phosphoric acid ester as pesticidally, e.g. insecticidally and/or acaricidally, active compound, in a ratio by weight of active compound to resin of e.g. about 0.25-2 : 1, and also containing a solid filler, and optionally a liquid filler.
Abstract:
IMPROVED PROCESS OF PRODUCING FOAMED MATERIALS FROM A COPOLYMERIZABLE MIXTURE OF UNSATURATED POLYESTERS AND A MONOMERIC POLYMERIZABLE VINYL COMPOUND EMPLOYING AS FOAMING AGENT A CARBONIC ACID ESTER ANHYDRIDE WHEREIN SAID FOAMING AGENT LIBERATES CARBON DIOXIDE WITHOUT THE APPLICATION OF EXTERNAL HEAT BY VIRTUE OF THE PRESENCE OF CERTAIN METAL COMPOUNDS.
Abstract:
The invention provides a four-component polymerization initiator for free-radical polymerization and a polymerizable composition comprising the initiator.
Abstract:
The invention relates to moulding compositions based on olefinically unsaturated polyesters, containing acid cellulose esters and polystyrene, which can be cured to give homogeneously coloured mouldings of low shrinkage.

Abstract:
Polyester moulding masses which contain unsaturated polyesters, monomeric unsaturated compounds copolymerizable therewith, magnesium oxide, fillers and catalysts are characterized in that they contain as unsaturated polyesters, at least in part, unsaturated polyesters which have been reacted with magnesium compounds in such quantities that they contain at least 0.05% by weight of magnesium incorporated in salt-like form. The unsaturated polyesters are formed from the normal acid and alcohol components and allyl and vinyl compounds are employed as the comonomers. The magnesium compounds that are reacted with the unsaturated polyesters may be selected from magnesium oxide, magnesium hydroxide, magnesium salts of organic acids such as magnesium formate and acetate, magnesium salts of halogenated acetic acids, magnesium propionate, magnesium acetyl-acetonate, magnesium acetoacetate, magnesium carbonate, basic magnesium carbonate and magnesium alcoholate. The reaction of the magnesium compound with the unsaturated polyester is preferably carried out at 60 DEG to 190 DEG C. in an inert gas atmosphere. Conventional inhibitors, catalysts and fillers are added to the moulding masses. In the examples (1) the unsaturated polyester is formed from maleic and phthalic anhydrides, butane1,3-diol and ethylene glycol and it is then reacted with magnesium oxide, and the product dissolved in styrene and (2) the unsaturated polyester is formed from maleic and phthalic anhydrides and propylene glycol and it is then reacted with magnesium ozide and the product dissolved in styrene.
