Abstract:
Polymer dispersed polyol having a vinyl polymer dispersed in polyol, the vinyl polymer prepared from vinyl monomers comprising 5 to 80 wt % of acrylamide compound (A) represented by the formula (1):CH.sub.2 .dbd.CR.sup.1 CONR.sup.2 R.sup.3 ( 1)wherein R.sup.1, R.sup.2 and R.sup.3 are a hydrogen atom or hydrocarbon group having 1 to 10 carbon atoms,0 to 70-wt % of one or more monomer (B) selected from acrylonitrile and methacrylonitrile,0 to 95 wt % of a vinyl monomer (C) which is copolymerizable with (A) and (B), and is one or more compounds selected from the group consisting of:(1) an aromatic vinyl monomer,(2) a compound represented by the formula (3):CH.sub.2 .dbd.CR.sup.7 --COO--R.sup.8 ( 3)(3) a compound represented by the formula (4):CH.sub.2 .dbd.CR.sup.9 --OCO--R.sup.10 ( 4)(4) a compound represented by the formula (5):CH.sub.2 .dbd.CR.sup.11 --COO--R.sup.12 --NR.sup.13 R.sup.14( 5)wherein, in the formulas (3) to (5), R.sup.7, R.sup.9 and R.sup.11 are a hydrogen atom or methyl group, R.sup.8 and R.sup.10 are an allyl group having 1 to 20 carbon atom, R.sup.12 is an alkylene group having 1 to 6 carbon atoms, R.sup.13 and R.sup.14 are a hydrogen atom or alkyl group having 1 to 6 carbon atoms and are not simultaneously a hydrogen atom, and(5) acrylic ester and methacrylic ester except the compounds represented by the formulas (3) and (5), and with the exception of .alpha.,.beta.-ethylenically unsaturated carboxylic anhydride, wherein 95 to 20 wt % of the vinyl monomers for preparing the vinyl polymer is composed of the total amount of (B) and (C);and a) when (C) is 0 wt %, (A) is a vinyl monomer containing an acrylamide derivative represented by the formula (2):CH.sub.2 .dbd.CR.sup.4 CONR.sup.5 R.sup.6 ( 2)wherein R.sup.4, R.sup.5,and R.sup.6 are a hydrogen atom or hydrocarbon group having 1 to 10 carbon atoms, and not simultaneously a hydrogen atom, and b) when (C) contains 5 to 60 wt % styrene, (C) further contains one or more compounds selected from the group consisting of the above formulas (3) to (5), acrylic ester or methacrylic ester except the compounds represented by formulas (3) to (5), and the amount of (B) and (C) except styrene is 15 to 90 wt %, and said polyol comprising 5 to 50 wt % of the vinyl polymer.
