Abstract
A composite material containing a thermoplastic material and a non-functional aromatic end group-containing polymer is disclosed. Also disclosed are methods of making and use the composite materials.
Claims13
A composite material comprising:
- a thermoplastic material;
- and,
- a liquid rubber;
- wherein the liquid rubber has a glass transition temperature of less than 25° C., a weight average molecular weight of ≧1,069 g/mol and comprises polymer chains that have one or more non functional aromatic terminal end-group;
- wherein the thermoplastic material is a thermoplastic polymer and wherein the liquid rubber is miscible with the thermoplastic material in a liquid state and immiscible with the thermoplastic material in a solid state.
2 more elements
A method far preparing a composite material, comprising:
- (a) providing a thermoplastic material;
- (b) providing a liquid rubber;
- and,
- (c) combining the liquid rubber with the thermoplastic material;
- wherein the liquid rubber has a glass transition temperature of less than 25° C., a weight average molecular weight of ≧1,069 g/mol and comprises polymer chains that have one or more non functional aromatic terminal end-group;
- wherein the liquid rubber is miscible in the thermoplastic material in a liquid state and immiscible in the thermoplastic material in a solid state.
3 more elements
A method for improving toughness of a thermoplastic material, comprising:
- providing a combination of a thermoplastic material and a liquid rubber;
- wherein the liquid rubber has a glass transition temperature of less than 25° C., a weight average molecular weight of ≧1,069 g/mol and comprises polymer chains that have one or more non functional aromatic terminal end-group;
- wherein the liquid rubber is miscible in the thermoplastic material in a liquid state and immiscible in the thermoplastic material in a solid state and wherein the toughness of the combined thermoplastic material and liquid rubber is greater than the toughness of the thermoplastic material in the absence of the liquid rubber.
