Abstract
Improving the properties of polymer materials by incorporating into a polymer material an effective amount of a modifying agent, preferably trans-4-tertbutyl-1-phenylcycolhexanol. Properties such as melting point, elastic modulus and softening temperature are improved.
Claims19
A method for enhancing the elastic modulus of a polymer material, which method comprising:
- forming a melt of said polymer material;
- adding an effective amount of a modifying agent to the melt, which modifying agent is represented by the formula:
- wherein R is a bulky C3 to C10 alkyl group and Ar is an aryl group;
- agitating said modified melt for an effective amount of time so that substantially all of said modifying agent dissolves in said melt, thereby resulting in a modified melt;
- solidifying said modified melt thereby resulting in the modifying agent precipitating in the form of nanoparticles dispersed throughout said polymer material and producing a modified polymer material having a higher elastic modulus compared to the starting polymer material.
