Title: Michael Chia-Chao Chen: Innovator in Polypropylene Polymers

Introduction

Michael Chia-Chao Chen is a notable inventor based in Bellaire, TX (US). He has made significant contributions to the field of polypropylene polymers, holding a total of 5 patents. His work focuses on enhancing the properties and applications of polypropylene, making it more versatile for various industrial uses.

Latest Patents

One of his latest patents involves a polypropylene homopolymer synthesized from a metallocene catalyst system. This invention details methods of forming the homopolymer, which boasts an aluminum and chlorine recoverables value of less than 25 ppm and a xylene solubles of less than 1 wt % relative to the total weight of the homopolymer. The resulting homopolymer exhibits desirable properties, including a heat deflection temperature at 0.45 MPa ranging from 90°C to 110°C, and a molecular weight distribution (MWD) value between 1.7 and 5.0. These characteristics make the homopolymer particularly suitable for films, especially capacitor films.

Another significant patent relates to oriented films made from improved crystalline polypropylene polymers. This invention focuses on films that comprise crystalline polypropylene polymer compositions containing both propylene homopolymers and propylene copolymers. The compositions are prepared using metallocene catalyst systems that involve the sequential or parallel polymerization of propylene homopolymers and copolymers. The resulting polymers are excellent for producing biaxially oriented films, which have a broader processability range and can be evenly stretched at lower temperatures compared to traditional polypropylene polymers.
