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.
Claims31
An engineered particle comprising:
- a) a plurality of polymeric chains comprising a thermoplastic polymer backbone comprised of one or more thermoplastic polymers;
- and
- b) a cross-linking network comprising one or more chemical having one or more reactive group, and a cross-linking agent capable of polymerizing said chemicals via the reactive group,
- wherein (a) and (b) together form an inter-penetrating polymer network.
