Title:
VERY THIN POLYMER FILM AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH03157163
Kind Code:
A
Abstract:
PURPOSE: To improve the chemical stability and heat resistance of a very thin polymer film of 10-1,000 thickness by forming the film by spin coating or the Langmuir-Elodgett's technique with a methacrylic ester polymer contg. repeating units of specified methacrylic ester.
CONSTITUTION: A soln. contg. 0.1-20mg/C methacrylic ester polymer having repeating units of methacrylic ester represented by formula I (where R is 3-12C branched alkyl, 3-12C cycloalkyl, 2-6C substd. alkyl having 3-14C cyclic substituents, etc.) is prepd. and applied by spin coating at 1,000-15,000 rotational frequency to form a very thin polymer film of 10-1,000 thickness. This film has superior chemical stability, insulating property and mechanical strength.
