Embodiment Construction

[0034] In this specification and the following claims, a number of terms are referred to, which are defined to have the following meanings.

[0035] Unless the context clearly stipulates otherwise, when the present invention refers to a substance, it includes not only the specific substance itself, but also the class of substances to which the substance belongs.

[0036] "Optional" means that the subsequently described event or circumstance can or cannot occur, and that description includes instances where the event occurs and instances where it does not.

[0037] As used herein, "combination" includes mixtures, copolymers, reaction products, blends, composites, and the like.

[0038] The endpoints of all ranges enumerating the same property are independently combinable and include the quoted endpoints. Expressions like "greater than about" or "less than about" are inclusive of the stated endpoints, eg "greater than about 3.5" includes the value 3.5.

Abstract

A polymer composition is disclosed, which comprises a matrix polymer, a fluoropolymer that may be at least partially encapsulated by an encapsulating polymer, and a filler. Methods for making the polymer compositions and articles made of such compositions are also disclosed. The compositions and article can have improved tensile modulus, ductility, and / or impact properties.

Description

[0001] This application is a divisional case of an invention patent application with the application date of December 29, 2004, the application number 200480042173.4 (PCT / US2004 / 043593), and the title "polymer composition and its preparation method and products prepared therefrom" Apply. [0002] Cross References to Related Applications [0003] This application claims priority to US Patent Application Serial No. 10 / 748,393, filed December 30, 2003, which is hereby incorporated by reference in its entirety. Background of the invention [0004] The present disclosure relates to polymer compositions, methods of synthesizing the polymer compositions, and articles made from the compositions. [0005] Many polymer-based articles are prepared by injection molding or other molding methods. In order to obtain good mechanical properties (such as high modulus), many methods have been tried, such as the use of fillers to reinforce the polymer. Different types of fillers are used, such...
