RESIN BLEND

摘要

PURPOSE: A resin mixture is provided to improve surface hardness and mechanical properties, and to reduce process time, improve productivity, and reduce manufacture costs. CONSTITUTION: A resin mixture has a first resin; and a second resin which has a hydrophilic portion represented by chemical formula 1, in the main chain thereof, and has a difference of 0.1-20 mN/m in surface energy with the first resin; and can form a separated layer structure. In chemical formula 1, each of R^a-R^d is independently C1-16 alkyl; and n is a number from 1-100. The difference between the first resin and the second resin is 0.1-3000 pa*s at a shearing rate of 100-1000 s^(-1) and process temperature of the resin mixture.
