摘要：
The invention relates to 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. The hardenable two part acrylic composition comprises an acrylic polymer composition first part and an acrylic monomer composition second part. The acrylic polymer composition first part comprises a first type of acrylic polymer particles characterized in that 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 comprise emulsion polymerised acrylic polymer particles of particle size between 10 and 2000nm. The invention also extends to 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.
