Abstract

Disclosed are compositions for anchoring materials in or to concrete or masonry. The compositions preferably comprise alkylacrylate ester monomer and a copolymer of alkylacrylate ester and methacrylic acid monomers, and free-radical catalyst.

Claims

exact text as granted — not AI-modified
1 . A composition for anchoring materials in or to concrete or masonry, which composition comprises:
 a. Alkylacrylate ester monomer;   b. A copolymer or alkylacrylate ester and methacrylic acid monomers;   c. A filler; and   d. A free-radical catalyst.   
   
   
       2 . The composition of  claim 1  wherein the polymer to monomer ratio is in the range of about 1 to 9 to about 2.5 to 1 by weight. 
   
   
       3 . The composition of  claim 1  wherein the polymer to monomer ratio is in the range of about 1 to 4 to about 1 to 2.5 by weight. 
   
   
       4 . The composition of  claim 1  wherein the combination of monomer and copolymer comprises about 20% to about 90% of the composition. 
   
   
       5 . The composition of  claim 1  wherein the combination of monomer and copolymer comprises about 20% to about 45% of the composition. 
   
   
       6 . The composition of  claim 1  wherein the filler comprises from about 10% to about 90% by weight of the composition. 
   
   
       7 . The composition of  claim 1  wherein the filler comprises from about 40% to about 80% by weight of the composition. 
   
   
       8 . The composition of  claim 1  further comprising a chain transfer agent. 
   
   
       9 . The composition of  claim 1  further comprising a free-radical inhibitor. 
   
   
       10 . The composition of  claim 1  further comprising an activator. 
   
   
       11 . A composition for anchoring materials in or to concrete or masonry that is made by mixing a first composition, which first composition comprises:
 a. A solution of methacrylate ester monomer and methacrylate ester/methacrylic acid copolymer; and   b. A filler; and   
     a second composition, which second composition comprises:
 a. A free-radical catalyst. 
 
   
   
       12 . The composition of  claim 11  wherein the polymer to monomer ratio is in the range of about 1 to 9 to about 2.5 to 1 by weight. 
   
   
       13 . The composition of  claim 11  wherein the polymer to monomer ratio is in the range of about 1 to 4 to about 1 to 2.5 by weight. 
   
   
       14 . The composition of  claim 11  wherein the monomer/copolymer solution comprises about 20% to about 90% of the composition. 
   
   
       15 . The composition of  claim 11  wherein the monomer/copolymer solution comprises about 20% to about 45% of the composition. 
   
   
       16 . The composition of  claim 11  wherein the first composition further comprises a chain transfer agent. 
   
   
       17 . The composition of  claim 11  further comprising a free-radical inhibitor. 
   
   
       18 . The composition of  claim 11  further comprising an activator. 
   
   
       19 . The composition of  claim 11  wherein the second composition further comprises a filler
