Gregory Peterson, Senior Capstone Seminar Controlled living anionic polymerization was employed to synthesize tetrablock copolymers in order to determine their compatibilizing ability in polymer
effectiveness in a model polymer blend systemGregory Peterson, Senior Capstone Seminar Controlled living anionic polymerization was employed to synthesize tetrablock copolymers in order to determine their compatibilizing ability in polymer blends. The tetrablocks were prepared with alternating polystyrene and polybutadiene blocks and goal block molecular weights of 5K and 10K. The copolymers were characterized with GPC and NMR, which demonstrated their monodisperse nature and block content. The tetrablock’s

polymerization to make various homopolymers and di-, tri-, and tetra-block copolymers of butadiene and styrene. We also have been synthesizing many new homopolmer, block copolymer, and random copolymer materials using ROMP techniques with norbornene and oxanorbornene monomers we have synthesized in house. Copolymer Compatibilization of Polymer Blends Copolymers have often been used to compatibilize polymer blends through favorable interactions with the blend domains. One monomer of the copolymer will

You Ask, We Answer: What is public transportation like around PLU? Posted by: shortea / October 20, 2023 October 20, 2023 While PLU’s Campus is neither in an urban or rural area, our middle of the road residential location of Parkland has plenty of public transportation options through Pierce Transit. Just a block from campus sits the Parkland Transit Center. The two main bus options here include Route 45 and Route 55. Route 45 will get you into downtown Tacoma typically in under 45 minutes

Sukhbir Randhawa, Senior Capstone Seminar Many different factors cause DNA damage in cells. UV radiation is one of the major factors; if a cell's DNA repair system does not keep repairing the
other a phenyl side group. NMR analysis of the polymers demonstrated a cis to trans ratio ranging from 1.2:1 to 1.7:1. Gel permeation chromatography was used to measure molecular weight and polydispersity indices. The polymer’s polydispersities were found to be narrow with values of less than 1.07. The diblock copolymers gave two glass transition (Tg) temperatures corresponding to the blocks of the copolymers with the higher Tg block shifted to a lower value relative to the homopolymer due to the
