Example 1

In a flask equipped with stirrer, condenser, nitrogen purge and temperature controller was reacted:

Ingredientswt.
1.)n-pentyl propionate (Dow Chemical, Midland MI)37.6
2.)Glycidyl methacrylate (Dow Chemical, Midland MI)85.5
3.)Di-t-amyl peroxide (Sigma-Aldrich Corp. Milwaukee WI)5.4
4.)Di-t-amyl peroxide (Sigma-Aldrich Corp. Milwaukee WI)0.2

#1 was added to the flask and heated to 152° C. under nitrogen. #2 and #3 were combined and added slowly to reaction flask over 5.5 hours. This was let react and additional 0.5 hours, then #4 added, let react for 1.0 hour then cooled to yield a 69.4% solution of polyglycidyl methacrylate. This solution was dried for 4 hrs @ 120° C. in a forced air oven to yield 100% dried polyglycidyl methacrylate.

Example 4

In a flask equipped with stirrer, condenser, nitrogen purge and temperature controller was reacted:

Ingredientswt.
1.)n-pentyl propionate (Dow Chemical, Midland MI)36.1
2.)SR324 Stearyl methacrylate (Sartomer Co., Exton PA)94.0
3.)Glycidyl methacrylate (Dow Chemical, Midland MI)6.0
4.)Di-t-amyl peroxide (Sigma-Aldrich Corp. Milwaukee WI)2.7
5.)Di-t-amyl peroxide (Sigma-Aldrich Corp. Milwaukee WI)0.5

#1 was added to the flask and heated to 152° C. under nitrogen. #2, #3 and #4 were combined and added slowly to reaction flask over 3.5 hours. This was let react and additional 1.0 hours, #5 added, let react for 1.5 hour then cooled to yield a 69.7% solution of polystearyl methacrylate-co-glycidyl methacrylate with a melt point of 31.1° C. and 83.8 J/g latent heat.

Example 6

Various polymeric PCMs were made similar to example 4 above, but the mol. wt. was varied by changing the amount of peroxide initiator or changing the polymerization solution solids.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
