Foaming product of blend of styrene type polymer and acrylic polymer

摘要

(57) Abstract Density is lower than the foaming product which is produced from only the styrene polymer, at least 50 weight % 50 where it possesses the average molecular weight under 90% of the styrene type polymer and this styrene type polymer weight % from the polymer blend which includes the acrylic polymer below the foaming product which possesses the independent cell structure which was formed.
