Abstract
Copolymers for use in a digital manufacturing process, in particular support materials for use in a digital manufacturing process comprising such copolymers. More particularly, the invention is directed to a copolymer, a support material based on the the copolymer, the use of the copolymer in a digital manufacturing process, a method for preparing the copolymer and a method for building a 3D-model by using a support material comprising the copolymer.
Claims13
A copolymer comprising
- a plurality of carboxyl monomer units derived from methacrylic acid monomers (MM);
- a plurality of phenyl monomer units;
- a plurality of first carboxylate ester monomer units derived from alkyl (meth-)acrylate monomers;
- and
- a plurality of second carboxylate ester monomer units derived from ethylhexyl acrylate monomers;
- wherein the first and the second carboxylate ester monomer units differ in their structural formula, wherein relative amounts of the monomer units are as follows:
- 35-45 wt % of the carboxyl monomer units derived from methacrylic acid monomers (MAA);
- 25-30 wt % of the phenyl monomer units;
- 10-15 wt % of the first carboxylate ester monomer units derived from alkyl methacrylate monomers,
- 12-20 wt % of the second carboxylate ester monomer units derived from ethylhexyl acrylate monomers;
- based on a weight of the copolymer.
