Abstract
Thermoplastic polymer particles directly cross-linked together or cross-linked via a separate and independent polymer network to form an inter-penetrating network are disclosed herein, along with methods of manufacturing and use as interleaf tougheners of pre-pregs and composite articles.
Claims9
An engineered cross-linked particle comprising:
- a) a plurality of thermoplastic polymer chains, each comprising a thermoplastic polymer backbone;
- and
- b) a cross-linking network created by reacting one or more compounds having one or more reactive groups with a cross-linking agent,
- wherein the thermoplastic polymer chains and the cross-linking network together form an inter-penetrating polymer network, and the thermoplastic polymer chains are entangled with the cross-linking network.
