Description
Oppfinnelsen vedrører en kolloidal blanding til anvendelse som krympningsnedsettende tilsetning til malein- og/ eller fumarsyrepolyestere. The invention relates to a colloidal mixture for use as a shrinkage reducing additive to maleic and/or fumaric acid polyesters.
Det er funnet at polyetylen og ABS-harpikser opp-løser seg eller sveller i varmen til malein- og/eller fumarsyrepolyestere på-polymeriserbare monomere som sbyren, a-metylstyren og vinyltoluen, således at disse blandinger etter avkjøling, eventuelt under omrøring, danner mer eller mindre viskøse kolloidale blandinger. Fra disse blandinger kan eventuelt overskudd av monomere avsuges, idet det dannes konsentrerte, lett smuldrende blandinger som eventuelt kan knuses. It has been found that polyethylene and ABS resins dissolve or swell in the heat to maleic and/or fumaric acid polyesters onto polymerizable monomers such as sbyrene, α-methylstyrene and vinyltoluene, so that after cooling, possibly during stirring, these mixtures form more or less viscous colloidal mixtures. Any surplus of monomers can be extracted from these mixtures, as concentrated, easily crumbly mixtures are formed which can possibly be crushed.
Før avkjølingen kan blandingene eventuelt tilsettes pigmentdispersjoner. Ved omrøring kan pigmentet lett fordeles meget jevnt, således at det også i de avkjølte vis-køse eller eventuelt smuldrebare kolloidale blandinger kan foreligge i fin og jevn fordeling. Before cooling, pigment dispersions can optionally be added to the mixtures. By stirring, the pigment can easily be distributed very evenly, so that it can also be present in a fine and even distribution in the cooled viscous or possibly crumbly colloidal mixtures.
De kolloidale blandinger ifølge oppfinnelsen er spesielt verdifulle som tilsetninger til blandinger av malein-og/eller fumarsyrepolyestere og på-polymeriserbare monomere, The colloidal mixtures according to the invention are particularly valuable as additives to mixtures of maleic and/or fumaric acid polyesters and on-polymerizable monomers,
da derved ved herdningen av polyesterblandinger krympningen nedsettes meget sterkt, og man kan få formlegemer med spesielt glatte og glinsende overflater. as thereby, during the curing of polyester mixtures, the shrinkage is greatly reduced, and molded bodies with particularly smooth and shiny surfaces can be obtained.
Oppfinnelsen vedrører altså en kolloidal blanding til anvendelse som krympningsnedsettende tilsetning til malein- og/eller fumarsyrepolyestere, bestående av The invention thus relates to a colloidal mixture for use as a shrinkage-reducing additive to maleic and/or fumaric acid polyesters, consisting of
a) 10-80 vekt-% polyetylen eller ABS-harpiks, og a) 10-80% by weight polyethylene or ABS resin, and
b) 90-20 vekt-% styren, a-metylstyren eller vinyltoluen, idet blandingen er karakterisert ved at den er fremstilt ved at polymeren a) er blitt oppløst eller svellet under oppvarming i monomeren b) eventuelt med etterfølgende tilsetning av pigmentdispersjoner, hvoretter blandingen, eventuelt under omrøring, er blitt avkjølt, eventuelt overskudd av den monomere frasugd og blandingen eventuelt pulverisert . b) 90-20% by weight styrene, α-methylstyrene or vinyltoluene, the mixture being characterized by the fact that it is produced by the polymer a) having been dissolved or swollen during heating in the monomer b) possibly with the subsequent addition of pigment dispersions, after which the mixture , optionally while stirring, has been cooled, any excess of the monomer sucked off and the mixture optionally pulverized.
Denne anvendelse av de kolloidale blandinger ifølge oppfinnelsen medfører med hensyn til de nevnte virk-ninger et fremskritt i forhold til den kjente tilsetning av finpulverisert polyetylen (sml. f.eks. DAS 1.192.820) og poly-metylmetacrylatoppløsninger ifølge belgisk patent nr. 700.910. This use of the colloidal mixtures according to the invention entails, with regard to the aforementioned effects, an advance compared to the known addition of finely powdered polyethylene (cf. e.g. DAS 1,192,820) and polymethyl methacrylate solutions according to Belgian patent no. 700,910 .
I følgende eksempler omtales fremstillingen ifølge oppfinnelsen av forskjellige kolloide blandinger. In the following examples, the preparation according to the invention of various colloidal mixtures is discussed.
