Abstract: A process is disclosed for continuously producing expandable styrene polymers by polymerising styrene in the presence of expanding agents in three steps: (a) prepolymerising styrene in the mass; (b) dispersing the prepolymer in an aqueous phase; and (c) polymerising the prepolymer in an aqueous suspension.

Abstract: The invention relates to fibre composite materials comprising a modified vinyl ester urethane resin and reinforcing fibres. The resin is a product of the reaction of A) a polyfunctional isocyanate, B1) a polyamine, optionally mixed with B2) a polyhydric alcohol, and C) a hydroxyalkyl (meth)acrylate, dissolved in D) an unsaturated monomer.

Abstract: The invention relates to a process for the preparation of unsaturated polyester resins having good styrene compatibility from maleic acid, phthalic acid, propylene glycol and dipropylene glycol with a molar maleic acid: phthalic acid ratio of between 1:0.05 and 1:0.45 and with a molar maleic acid: dipropylene glycol ratio of from 1:0.05 to 1:0.6, where, in a first step, phthalic acid or phthalic anhydride is esterified by means of an excess of glycols, and subsequently, in a second step, fumaric acid, maleic acid or maleic anhydride and any remaining glycols are added and esterified. The polyester resins can be used for the preparation of SMC and BMC formulations

Abstract: Unsatd. polyester resins (I) contg. maleic acid (II), phthalic acid (III), propylene glycol (IV) and dipropylene glycol (V) units, with mol. ratio (II):(III) from 1:0.05 to 1:0.45 and mol. ratio (II):(V) from 1:0.05 to 1:0.6, are mfd. by (a) reaction of (III) with excess glycols, followed by (b) addn. of (II) or its anhydride or fumaric acid and any remaining glycol, and esterification. Pref. mol. ratio glycol:(III) in first stage is from 2:1 to 22:1; acid no. at end of (a) is pref. below 10; at end of (b) prod. pref. has acid no. 10-40, OH-no. 10-60, and melt viscosity 300-1500 mPa.s at 150 deg.C.

Abstract: The prepn. of pigmented, curable moulding materials by mixing (a) 100 pts. wt. of an unsatd. polyester; (b) 30-150 pts. wt. of a monomer copolymerisable with (a); (c) 1-100 pts. wt. of a thermoplastic polymer; and (d) 0.1-15 pts. wt. of a colour pigment; and opt. (e) the usual additives. The pigment is dispersed in at least one part of the thermoplastic polymer using an extruder at temps. in the range of the m.pt. of the thermoplastics. Pref. the dispersion process lasts no more than 5 mins.. USE/ADVANTAGE - The moulding materials can be used to form coloured moulded prods.. No pigment sepn. occurs due to the use of two polymers, and the components can be mixed in the usual mixing devices.
