Abstract
Compositions which are curable by, for example, exposure to radiation to form useful articles such as three-dimensionally printed objects are prepared using multistage polymers, polymerizing organic substances and (meth)acrylic polymers. The multistage polymer is effective to toughen and impact modify the cured articles, yet the compositions prior to curing are relatively low in viscosity and agglomerate content even at high loadings of multistage polymer.
Claims11
A method of making a cured article, comprising curing a curable composition comprising component (a), component (b), and component (c), wherein:
- a) component (a) is one or more multistage polymers;
- b) component (b) is one or more (meth)acrylic polymers (P1), which is or are different in composition from any (meth)acrylic polymer present as part of the multistage polymer(s) of component (a);
- and
- c) component (c) is one or more monomeric polymerizing organic substances;
- and wherein the curable composition is cured by exposing the curable composition to radiation.
A method of making a three-dimensional article, comprising printing the three-dimensional article using a curable composition comprised of component (a), component (b), and component (c), wherein:
- a) component (a) is one or more multistage polymers;
- b) component (b) is one or more (meth)acrylic polymers (P1);
- and
- c) component (c) is one or more monomeric polymerizing organic substances.
