Open the CIPO recordAbstract From the Canadian patent
A self-reinforced polymer composite in the form of a non-laminated shaped article is prepared by (a) melt blending (1) a matrix polymer which is a melt processable flexible chain polymer or first liquid crystal polymer (LCP) and (2) a fiber forming melt processable second LCP under high strain mixing conditions inducing fiber formation, cooling and stretching the resulting blend and (b), shaping the resulting blend by injection molding or extrusion at a temperature which is above the minimum melt processing temperature of the matrix polymer but below that of the fiber forming second LCP. By shaping at a temperature below the minimum processing temperature of the fiber-forming LCP the fiber …

Why it's free to use
- Filed January 19, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 19, 2013.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
