Abstract
Acrylic compositions filled with alumina trihydrate with the mixed ester reaction product of propylene glycol methacrylate and phosphorus pentoxide have superior mechanical properties and ease of manufacture. In such acrylic compositions, the ester reaction product imparts superior properties by acting as a very effective coupling agent between the alumina trihydrate filler and the acrylic matrix.
Claims8
A reaction curable resin composition comprising a curable component, a polymerization initiator for curing the curable component, an inorganic filler including alumina trihydrate and a phosphoric acid ester of methacrylic or acrylic acid having the formula:
- CH.sub.2 .dbd.C(R.sub.1)--COO(CH(R.sub.2)CH(R.sub.3)O)n!y--PO(OH)x
- where R.sub.1 =H or CH.sub.3 ;
- R.sub.2 =H or CH.sub.3 ;
- R.sub.3 =CH.sub.3 or H;
- R.sub.2 is not the same as R.sub.3 ;
- n is 2 to 8;
- x is 1 or 2, and x+y=3.
