摘要:
A hardenable two part acrylic composition, a polymer component of the two part hardenable composition and a method of producing a polymer component of the two part composition are disclosed. The hardenable two part acrylic composition includes an acrylic polymer composition first part and an acrylic monomer composition second part. The acrylic polymer composition first part includes a first type of acrylic polymer particles wherein each first type of acrylic polymer particle is formed of a network of coalesced emulsion polymerized acrylic microparticles or is microporous. The acrylic polymer composition may include emulsion polymerised acrylic polymer particles of particle size between 10 and 2000 nm and includes the use of acrylic polymer particles formed of a network of coalesced emulsion polymerized acrylic microparticles as a dough time reduction agent in a hardenable two part acrylic composition.

The hardenable two part acrylic composition includes an acrylic polymer composition first part and an acrylic monomer composition second part. The acrylic polymer composition first part includes a first type of acrylic polymer particles wherein each first type of acrylic polymer particle is formed of a network of coalesced emulsion polymerized acrylic microparticles or is macroporous. The acrylic polymer composition may include emulsion polymerised acrylic polymer particles of particle size between 10 and 2000 nm and includes the use of acrylic polymer particles formed of a network of coalesced emulsion polymerized acrylic microparticles as a dough time reduction agent in a hardenable two part acrylic composition.
摘要:
Branched polymers are prepared by mixing together monofunctional vinylic monomer with from 0.3 to 100% w/w of polyfunctional vinylic monomer and from 0.0001 to 50% w/w of chain transfer agent and thereafter reacting the mixture to form a polymer. The resulting branched polymers are soluble and may be used as component of surface coatings and inks as well as molding resins.
摘要:
A method of preparing a (meth)acrylate functionalised polymer comprising the steps of mixing together a monofunctional vinylic monomer with from 0.3-100% w/w (based on monofunctional monomer) of a polyfunctional vinylic monomer and from 0.0001-50% w/w of a chain transfer agent, reacting said mixture to form a polymer and terminating the polymerisation reaction before 99% conversion. The resulting polymers are useful as components of surface coatings and inks, as moulding resins or in curable compounds, e.g. curable moulding resins or photoresists.

摘要:
An embedment casting composition and a process of embedding a specimen in an acrylic polymer matrix is described. The composition comprises an acrylic copolymer and a suitable solvent. The acrylic copolymer is derived from 80-99% w/w methyl methacrylate, 0.1-10% w/w of a C3-C10 olefinically unsaturated acid co-monomer selected from carboxylic, phophonic, sulphonic or phosphinic acids and 0-10% w/w other suitable monomers and/or additives. A process of embedding a specimen in an acrylic polymer matrix, a cast of an embedded metal specimen, the use of an embedment composition for coating a specimen prior to an embedment coating process and use of an embedment composition as the copolymer resin component of an embedment slurry are also described.
